INA188 Datasheet PDF (High-Voltage Instrumentation Amplifier)

INA188 - High-Voltage Instrumentation Amplifier

Description

The INA188 is a precision instrumentation amplifier that uses TI proprietary auto-zeroing techniques to achieve low offset voltage, near-zero offset and gain drift, excellent linearity, and exceptionally low-noise density (12 nV/√Hz) that extends down to dc.

Features

1 Excellent DC Performance:.
Low Input Offset Voltage: 55 μV (max).
Low Input Offset Drift: 0.2 μV/°C (max).
High CMRR: 104 dB, G ≥ 10 (min).
Low Input Noise:.
12 nV/√Hz at 1 kHz.
0.25 μVPP (0.1 Hz to 10 Hz).
Wide Supply Range:.
Single Supply: 4 V to 36 V.
Dual Supply: ±2 V to ±18 V.
Gain Set with a Single External Resistor:.
Gain Equation: G = 1 + (50 kΩ / RG).
Gain Error: 0.007%.
