Preliminary Technical Data Low Cost, Precision JFET Input Operational Amplifier in TSOT ADA4000-1 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/μs Low voltage noise: 15 nV/√Hz Unity gain stable Wide bandwidth: 6 MHz 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 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. Figure 2. 8-Lead SOIC (R-8) 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.
