High-Speed, Low-Power Voltage Comparators
General Description
The MAX900-MAX903 high-speed, low-power, single/ dual/quad voltage comparators feature differential analog inputs and TTL-logic outputs with active internal pullups. Fast propagation delay (8ns typ at 5mV overdrive) makes the MAX900-MAX903 ideal for fast A/D converters and sampling circuits, line receivers, V/F converters, and many other data-discrimination applications. All comparators can be powered from separate analog and digital power supplies or from a single combined supply voltage. The analog input common-mode range includes the negative rail, allowing ground sensing when powered from a single supply. The MAX900-MAX903 consume 18mW per comparator when powered from +5V. The MAX900-MAX903 are equipped with independent TTL-compatible latch inputs. The comparator output states are held when the latch inputs are driven low. The MAX901 provides the same performance as the MAX900/MAX902/MAX903 with the exception of the latches. For newer, pin-for-pin compatible parts with the same speed and only half the power dissipation, see the MAX9201/MAX9202/MAX9203 data sheet. o 8ns (typ) Propagation Delay o 18mW/Comparator Power Consumption (+5V, typ) o Separate Analog and Digital Supplies o Flexible Analog Supply: +5V to +10V or 5V o Input Range Includes Negative Supply Rail o TTL-Compatible Outputs o TTL-Compatible Latch Inputs (Except MAX901)

Note 1: The input common-mode voltage and input signal voltages should not be allowed to go negative by more than 0.2V below VEE. The upper-end of the common-mode voltage range is typically VCC - 2V, but either or both inputs can go to a maximum of VCC + 0.2V without damage. Note 2: Tested for +4.75V < VCC < +5.25V, and -5.25V < VEE < -4.75V with VDD = +5V, although permissible analog power-supply range is +4.75V < VCC < +10.5V for single-supply operation with VEE grounded. Note 3: Specification does not apply to MAX901. Note 4: Guaranteed by design. Times are for 100mV step inputs (see Propagation Delay Characteristics in Figures 2 and 3). Note 5: Maximum difference in propagation delay between any of the four comparators in the MAX900-MAX903. Note 6: See Timing Diagram (Figure 2). Owing to the difficult and critical nature of switching measurements involving the latch, these parameters cannot be tested in a production environment. Typical specifications listed are taken from measurements using a high-speed test-jig. Note 7: ICC tested for +4.75V < VCC < +10.5V with VEE grounded. IEE tested for -5.25V < VEE < -4.75V with VCC = +5V. IDD tested for +4.75V < VDD < +5.25V with the worst-case condition of all four comparator outputs at logic low.

Applications Information
Circuit Layout
Because of the large gain-bandwidth transfer function of the MAX900-MAX903, special precautions must be taken to realize their full high-speed capability. A printed circuit board with a good, low-inductance ground plane is mandatory. All decoupling capacitors (the small 100nF ceramic type is a good choice) should be mounted as close as possible to the power-supply pins. Separate decoupling capacitors for analog VCC and for digital V DD are also recommended. Close attention should be paid to the bandwidth of the decoupling and terminating components. Short lead lengths on the inputs and outputs are essential to avoid unwanted parasitic feedback around the comparators. Solder the device directly to the printed circuit board instead of using a socket. pushes the output through the transition region cleanly, but applies a hysteresis in threshold seen at the input terminals.
TTL Output and Latch Inputs
The comparator TTL-output stages are optimized for driving low-power Schottky TTL with a fan-out of four. When the latch is connected to a logic high level or left floating, the comparator is transparent and immediately responds to changes at the input terminals. When the latch is connected to a TTL low level, the comparator output latches in the same state as at the instant that the latch command is applied, and will not respond to subsequent changes at the input. No latch is provided on the MAX901.
Power Supplies
The MAX900-MAX903 can be powered from separate analog and digital supplies or from a single +5V supply. The analog supply can range from +5V to +10V with VEE grounded for single-supply operation (Figures 1A and 1B) or from a split 5V supply (Figure 1C). The VDD digital supply always requires +5V. In high-speed, mixed-signal applications where a common ground is shared, a noisy digital environment can adversely affect the analog input signal. When set up with separate supplies (Figure 1C), the MAX900-MAX903 isolate analog and digital signals by providing a separate AGND (VEE) and DGND.
Input Slew-Rate Requirements
As with all high-speed comparators, the high gain-bandwidth product of the MAX900-MAX903 can create oscillation problems when the input traverses the linear region. For clean output switching without oscillation or steps in the output waveform, the input must meet minimum slew-rate requirements. Oscillation is largely a function of board layout and of coupled source impedance and stray input capacitance. Both poor layout and large-source impedance will cause the part to oscillate and increase the minimum slew-rate requirement. In some applications, it may be helpful to apply some positive feedback between the output and + input. This

Programmed, Variable-Alarm Limits
By combining two quad analog comparators with an octal 8-bit D/A converter (the MX7228), several alarm and limit-defect functions can be performed simultaneously without external adjustments The MX7228's internal latches allow the system processor to set the limit points for each comparator independently and update them at any time. Set the upper and lower thresholds for a single transducer by pairing the D/A converter and comparator sections.
