Audio applications and medical monitoring The AD8661/AD8662/AD8664 are rail-to-rail output, single- equipment can take advantage of the high input impedance, low supply amplifiers that use the Analog Devices, Inc., patented voltage, low current noise, and wide bandwidth. DigiTrim trimming technique to achieve low offset voltage. The AD8661/AD8662/AD8664 series features extended The single AD8661 is available in a narrow 8-lead SOIC package operating ranges, with supply voltages up to 16 V. It also and a very thin, dual lead, 8-lead LFCSP. The AD8661 SOIC features low input bias current, wide signal bandwidth, package is specified over the extended industrial temperature and low input voltage and current noise. range of 40C to +125C. The AD8661 LFCSP is specified over the industrial temperature range of 40C to +85C. The AD8662 The combination of low offset, very low input bias current, is available in a narrow 8-lead SOIC package and an 8-lead MSOP, and a wide supply range makes these amplifiers useful in a wide both specified over the extended industrial temperature range of variety of applications usually associated with higher priced JFET 40C to +125C. The AD8664 is available in a narrow 14-lead amplifiers. Systems using high impedance sensors, such as SOIC package and a 14-lead TSSOP, both with an extended photodiodes, benefit from the combination of low input bias industrial temperature range of 40C to +125C. current, low noise, low offset, and wide bandwidth. The wide operating voltage range meets the demands of high performance analog-to-digital converters (ADCs) and digital-to-analog 1 Protected by U.S. Patents 6,194,962 and 6,696,894. Rev.
