LF398AN/NOPB TI Instrumentation, OP Amps, Buffer Amps

The LF398AN/NOPB is a precision sample-and-hold amplifier from Texas Instruments featuring a high input impedance of 10^10 Ω and a fast acquisition time of 6 µs (max). It operates over a supply range of ±5V to ±18V and provides a hold step of 0.5 mV (typical). The device includes an internal hold capacitor and TTL/CMOS logic inputs for sample/hold control, simplifying design. It features low droop rate of 0.5 µV/ms and high accuracy. Housed in an 8-pin PDIP (N) package, it operates over 0°C to 70°C. Applications include data acquisition systems, analog-to-digital converter front-ends, signal processing systems requiring precise voltage storage, and analog memory circuits.
