¹Rail-to-rail output.

The AD8295 includes a high performance, programmable gain

instrumentation amplifier. Gain is set from 1 to 1000 with a

single resistor. The low noise and excellent common-mode

rejection of the AD8295 enable the part to easily detect small

signals even in the presence of large common-mode interference.

For a similar instrumentation amplifier without the associated

signal conditioning circuitry, see the AD8221 or AD8222 data

sheet.

GENERAL DESCRIPTION

The AD8295 contains all the components necessary for a

precision instrumentation amplifier front end in one small

4 mm × 4 mm package. It contains a high performance

instrumentation amplifier, two general-purpose operational

amplifiers, and two precisely matched 10 kΩ resistors.

The AD8295 is designed to make PCB routing easy and

efficient. The AD8295 components are arranged in a logical

way so that typical application circuits have short routes and

few vias. Unlike most chip scale packages, the AD8295 does not

have an exposed metal pad on the back of the part, which frees

additional space for routing and vias. The AD8295 comes in a

4 mm × 4 mm LFCSP that requires half the board space of an

8-pin SOIC package.

The AD8295 operates on both single and dual supplies and is

well suited for applications where 10 ꢀ input voltages are

encountered. Performance is specified over the entire industrial

temperature range of −40°C to +85°C for all grades. The

AD8295 is operational from −40°C to +125°C; see the Typical

Performance Characteristics section for expected operation up

to 125°C.
