Product Introduction
The OPA2188 operational amplifier uses auto-zero technology to provide low offset voltage (25 μV, maximum) and near-zero drift over time and temperature range. These miniature, high-precision, low quiescent current amplifiers offer high input impedance and rail-to-rail outputs that swing within 15 mV of the supply rails. The input common-mode range includes the negative supply rail. Single or dual supplies can be used in the range of +4.0 V to +36 V (±2 V to ±18 V). The OPA2188 is available in the miniature small-outline package (MSOP)-8 and small-outline package (SO)-14. This device is specified for operation from –40 °C to +105 °C.
