Product Details
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 has been 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 up 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 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.
The AD8295 operates on both single and dual supplies and is well suited for applications where ±10 V 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.
