Low-Voltage Op Amps Suit Battery-Powered Applications

The AD8631 low-voltage operational amplifier in an SOT-23-5 package operates on single supply voltages as low as 1.8V. Both the AD8631 and AD8632 are rail-to-rail input and output bipolar amplifiers with a 3V/µs slew rate, gain bandwidth of 4 MHz, and a typical voltage offset of 0.8 mV from a 1.8V supply. The AD8631 single is available in 5-lead, SOT-23 surface-mount packages. The dual AD8632 is available in eight-lead SOIC and µSOIC packages. Pricing starts at $0.64 each/1,000.
