Low Power, 3.6 MHz, Low Noise, Rail-to- Rail Output, Operational Amplifiers Data Sheet ADA4691-2/ ADA4691-4/ ADA4692-2/ ADA4692-4 FEATURES
The ADA4691/ADA4692 family is fully specified over the
Low power: 180 μA typical
extended industrial temperature range (−40°C to +125°C).
Very low input bias currents: 0.5 pA typical
The ADA4691-2 is available in a 10-lead LFCSP and a 9-ball
Low noise: 16 nV/√Hz typical
WLCSP. The ADA4692-2 is available in an 8-lead SOIC and 8-lead
3.6 MHz bandwidth
LFCSP. The ADA4691-4 is available in a 16-lead LFCSP. The
Offset voltage: 500 μV typical
ADA4692-4 is available in a 14-lead TSSOP. For pin configurations,
Low offset voltage drift: 4 μV/°C maximum
see the Pin Configurations section.
Low distortion: 0.003% THD + N 2.7 V to 5 V single supply or ±1.35 V to ±2.5 V dual supply 1 Available in very small 2 mm × 2 mm LFCSP packages ADA4692-2 VSY = ±2.5V A APPLICATIONS V = –1 TA = 25°C Photodiode amplifiers 0.1 Sensor amplifiers ) Portable medical and instrumentation (% N RL = 600Ω Portable audio: MP3s, PDAs, and smartphones + HD Communications T RL = 2kΩ 0.01 Low-side current sense ADC drivers Active filters Sample-and-hold 0.001 GENERAL DESCRIPTION 10 100 1k 10k 20k
