AD8661ARZ-REEL7

AD8661 is a rail-to-rail output, single supply amplifier that use the Analog Devices, Inc., patented DigiTrim® trimming technique to achieve low offset voltage. The combination of low offset, very low input bias current, and a wide supply range makes this amplifier useful in a wide variety of applications usually associated with higher priced JFET amplifiers. Systems using high impedance sensors, such as photodiodes, benefit from the combination of low input bias current, low noise, low offset, and wide bandwidth. The wide operating voltage range meets the demands of high performance analogue-to-digital converters (ADCs) and digital-to-analogue converters (DACs). It is widely used in application such as sensors, medical equipment, consumer audio, photodiode amplification, ADC drivers etc.
