The low bias current drift is well- that use the Analog Devices, Inc., patented DigiTrim trimming suited for precision I-to-V converters. The combination of technique to achieve low offset voltage. The AD8663/AD8667/ precision offset, offset drift, and low noise also make the op AD8669 feature an extended operating range with supply amps ideal for gain, dc offset adjust, and active filter in both voltages up to 16 V. They also feature low input bias current, instrumentation and medical applications. These low power low input offset voltage, and low current noise. op amps can be used in IR thermometers, pH and ORP instru- ments, pressure transducer front ends, and other sensor signal The combination of low offset, very low input bias current, and conditioning circuits that are used in remote or wireless a wide supply range makes these amplifiers useful in a wide variety applications. of applications usually associated with higher priced JFET ampli- fiers. Systems using high impedance sensors, such as photodiodes, The AD8663/AD8667/AD8669 are specified over the extended benefit from the combination of low input bias current, low industrial temperature range of 40C to +125C. The single noise, low offset, and wide bandwidth. AD8663 is available in a narrow 8-lead SOIC package and a very thin, 8-lead LFCSP. The dual AD8667 is available in a narrow The ability to operate the device for single (5 V to 16 V) or dual 8-lead SOIC package and an 8-lead MSOP. The quad AD8669 supplies (2.5 V to 8 V) supports many applications. The rail- is available in a 14-lead SOIC and 14-lead small TSSOP. to-rail outputs provide increased dynamic range to drive low Rev.
