These miniature, high-precision, low-quiescent current amplifiers offer high-input impedance and rail-to-rail output swing within 5 mV of the rails into high-impedance loads. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of 4.5 V to 36 V (±2.25 V to ±18 V). The single version of the OPAx187 device is available in microsize 8-pin VSSOP, 5-pin SOT-23, and 8-pin...
