Product SelectorRenesas instrumentation amplifiers (in-amps) and programmable gain instrumentation amplifiers (PGIAs) provide the precision and high performance needed in many industrial, test and measurement, data acquisition, and medical applications.
Instrumentation amplifiers are precision, integrated operational amplifiers that have differential input and single-ended or differential output. Some of their key features include very high common mode rejection ratio (CMRR), high open loop gain, low DC offset, low drift, low input impedance, and low noise. Programmable gain instrumentation amplifiers are specialized in-amps that have fixed gain levels. The appropriate gain level is selected by digital means.
In-Amps Key Features
- Extremely low supply currents
- <95μA max. supply current
- Rail-to-rail input/output
- Single supply 2.4V to 5.5V operation
- Operate above and below the rails
- Ground sensing option
- Compensated for a gain of 100 or more
Programmable Gain In-Amps Key Features
- Ultra-high precision front-end amplifier
- Zero-drift instrumentation amplifier
- 9-pin selectable gain options: AV = 1 to 1,000
- Rail-to-rail input/output
- Single-ended output (ISL2853x)
- Differential output (ISL2863x)
- RFI filtered inputs improve EMI rejection
