GENERAL DESCRIPTION

The AD8631 brings precision and bandwidth to the SOT-23-5

package at single supply voltages as low as 1.8 V and low supply

current. The small package makes it possible to place the AD8631

next to sensors, reducing external noise pickup.

The AD8631 and AD8632 are rail-to-rail input and output bipolar

amplifiers with a gain bandwidth of 4 MHz and typical voltage

offset of 0.8 mV from a 1.8 V supply. The low supply current and

the low supply voltage makes these parts ideal for battery-powered

applications. The 3 V/µs slew rate makes the AD8631/AD8632 a

good match for driving ASIC inputs, such as voice codecs.

The AD8631/AD8632 is specified over the extended industrial

(–40 C to +125 C) temperature range. The AD8631 single is

available in 5-lead SOT-23 surface-mount packages. The dual

AD8632 is available in 8-lead SOIC and µSOIC packages.
