GENERAL DESCRIPTION

The AD8228 operates on both single and dual supplies. Because

the part can operate on supplies up to ±±8 ꢀ, it is well suited for

applications where high common-mode input voltages are

encountered. The AD8228 is available in 8-lead MSOP and

SOIC packages.

The AD8228 is a high performance instrumentation amplifier

with very high gain accuracy. Because all gain setting resistors

are internal and laser trimmed, gain accuracy and gain drift

are better than can be achieved with typical instrumentation

amplifiers.

Performance is specified over the entire industrial temperature

range of −40°C to +85°C for all grades. Furthermore, the AD8228

is operational from −40°C to +±25°C. For a pin-compatible ampli-

fier with similar specifications, but with a gain range of ± to ±000,

see the AD822±.

Low voltage offset, low offset drift, low gain drift, high gain

accuracy, and high CMRR make this part an excellent choice

in applications that demand the best dc performance possible,

such as bridge signal conditioning.
