GENERAL DESCRIPTION
The MP7541B is a pin-compatible replacement which offers superior performance in latch-up and ESD protection versus the comparable 7541 and 7541A. The high ESD protection will reduce failures caused by mishandling. These devices are manufactured using patented advanced thin film resistors on a double metal CMOS process which result in ultra stable thin film and superior long life reliability and stability. The MP7541B incorporates a bit decoding technique yielding lower glitch, higher
speed and excellent accuracy over temperature and time. The MP7541B's outstanding features are: Stability: Both Integral Non-Linearity (INL) and DifferentialNon-Linearity (DNL) are rated at 0.2 ppm/C maximum. Monotonicity is guaranteed over the entire temperature range. Gain Temperature Coefficient (TCGE) is 2.0 ppm/C typical. Lower Sensitivity to Output Amplifier Offset: Multiplying DACs provide an output current into a virtual ground of the output op amp. Additional linearity error caused by the op amp is reduced by a factor of 3 in the MP7541B versus conventional R-2R DACs.

NOTES: 1 Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. 2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps (HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short transients outside the supplies of less than 20mA for less than 100s.
