The OPA4188 operational amplifier uses TI proprietary auto-zeroing techniques to provide low offset voltage (25 µV, maximum), and near zero-drift over time and temperature. These miniature, high-precision, low quiescent current amplifiers offer high input impedance and rail-to-rail output swing within 15 mV of the rails, making them ideal for industrial applications. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of 4 V to 36 V (±2 V to ±18 V).
