SBOS632 – SEPTEMBER 2015 INA188
Precision, Zero-Drift, Rail-to-Rail Out, High-Voltage Instrumentation Amplifier
1 Features 3 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/в€љHz) that extends down to dc. 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: …
