INA157U Datasheet

High-Speed, Precision Difference Amplifier


The INA157U is a high slew rate, G = 1/2 or G = 2 difference amplifier consisting of a precision op amp with a precision resistor network. The on-chip resis-tors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The input common-mode voltage range extends beyond the positive and negative supply rails. It operates on ±4V to ±18V supplies. INA157U Features • Designed For Low Cost• Low Offset Voltage: ±500µV max• Low Offset Drift: ±2µV/°C• Low Gain Error: ±0.05% max• Wide Bandwidth: 3MHZ• High Slew Rate: 14V/µS• Fast Settling Time: 3µS TO 0.01%• Wide Supply Range: ±4V TO ±18V• Low Quiescent Current: 2.4MA• So-8 Surface-Mount Package INA157U Applications • Differential Input Amplifier• Instrumentation Amplifier Building Block• G = 1/2 Amplifier• G = 2 Amplifier• Differential Current Receiver• Voltage-Controlled Current Source• Ground Loop Eliminator• Current Shunt Monitor
