Introduction
The AD8222 is a dual-channel, high performance instrumentation amplifier that requires only one external resistor per amplifier to set gains of 1 to 10,000. The AD8222 is the first dual-instrumentation amplifier in the small 4 mm×4 mm LFCSP. It requires the same board area as a typical single instrumentation amplifier. The smaller package allows a 2× increase in channel density and a lower cost per channel, all with no compromise in performance. The AD8222 can also be configured as a single-channel, differential output instrumentation amplifier. Differential outputs provide high noise immunity, which can be useful when the output signal must travel through a noisy environment, such as with remote sensors. The configuration can also be used to drive differential input analog-to-digital converters (ADCs). The AD8222 maintains a minimum CMRR of 80 dB to 4 kHz for all grades at G = 1. High CMRR over frequency allows the AD8222 to reject wideband interference and line harmonics, greatly simplifying filter requirements. The AD8222 also has a typical CMRR drift over temperature of just 0.07 μV/V/°C at G = 1. The AD8222 operates on both single and dual supplies and only requires 2.2 mA maximum supply current for both amplifiers. It is specified over the industrial temperature range of -40°C to +85°C and is fully RoHS compliant.
Features
- Two channels in small 4 mm×4 mm LFCSP
- Gain set with 1 resistor per amplifier (G = 1 to 10,000)
- Low noise 8 nV/√Hz at 1 kHz, 0.25 μV p-p (0.1 Hz to 10 Hz)
- High accuracy dc performance (B grade): 60 μV maximum input offset voltage, 0.3 μV/°C maximum input offset drift, 1.0 nA maximum input bias current, 126 dB minimum CMRR (G = 100)
- Excellent ac performance: 140 kHz bandwidth (G = 100), 73 μs settling time to 0.001%
- Differential output option (single channel): Fully specified, Adjustable common-mode output
- Supply range: ±2.3 V to ±18 V
Applications
- Multichannel data acquisition for ECG and medical instrumentation
- Industrial process controls
- Wheatstone bridge sensors
- Differential drives for High resolution input ADCs
- Remote sensors
