AD8662:  Low Noise, Precision 16 V CMOS, Rail-to-Rail Operational Amplifiers

Product Description

The AD8661/AD8662 are rail-to-rail output, single-supply amplifiers that use the Analog Devices patented DigiTrim® trimming technique to achieve low offset voltage. The AD8661/AD8662 feature extended operating ranges with supply voltages up to 16 V. They also feature low input bias current, wide signal bandwidth, and low input voltage and current noise.

The combination of low offset, very low input bias current, and a wide supply range make these amplifiers 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 ADCs and DACs. Audio applications and medical monitoring equipment can take advantage of the high input impedance, low voltage and current noise, and wide bandwidth.

The single AD8661 is available in an 8-lead SOIC_N package and an 8-lead LFCSP_VD. The AD8661 SOIC_N package is specified over the extended industrial temperature range from −40°C to +125°C. The AD8661 LFCSP_VD is specified over the extended industrial temperature range from −40°C to +85°C. The AD8662 is available in an 8-lead SOIC_N package and an 8-lead MSOP specified over the extended industrial temperature range from −40°C to +125°C.
