| Preliminary Technical Data FEATURES Very low offset voltage: 1 mV max Bias current: 10 pA max Small packaging, TSOT-23 lead-free 5 V to 15 V operation High slew rate: 20 V/s Low voltage noise: 15 nV/Hz Unity gain stable Wide bandwidth: 6 MHz Low Cost, Precision JFET Input Operational Amplifier in TSOT ADA4000-1 PIN CONFIGURATIONS Figure 1. 5-Lead TSOT (UJ-5) APPLICATIONS Reference gain/buffers Level shift/driving Active filters Power line monitoring/control Current/voltage sense or monitoring Data acquisition Sample-and-hold circuits Integrators Figure 2. 8-Lead SOIC (R-8) GENERAL DESCRIPTION The AD4004 is a JFET input operational amplifier featuring precision, very low bias current, and low power in a tiny package at a very attractive price. Combining high input impedance, low input bias current, wide bandwidth, and fast slew rate, the AD4000 is an ideal amplifier for driving A/D inputs and buffering D/A converter outputs. Additional applications for the AD4004 include electronic instruments; ATE amplification, buffering, and integrator circuits; Instrumentation quality photodiode amplification; fast precision filters (including PLL filters), utility functions like reference buffering, level shifting, control I/O interface, power supply control and monitoring functions.

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL RESISTANCE JA is specified for the worst-case conditions, that is, for a device in socket for PDIP packages; a device soldered in a circuit board for SOIC and TSSOP packages. Table 4.
