ADA4530-1ARZ-R7 General Description

The ADA4530-1 is a femtoampere (10⁻¹⁵ A) level input bias current operational amplifier suitable for use as an electrometer that also includes an integrated guard buffer. It has an operating voltage range of 4.5 V to 16 V, enabling it to operate in conventional 5 V and 10 V single supply systems as well as ±2.5 V and ±5 V dual supply systems.

Key Features

Low input bias current
- ±20 fA maximum at T_A = 25°C (guaranteed at production test)
- ±20 fA maximum at −40°C < T_A < +85°C
- ±250 fA maximum at −40°C < T_A < +125°C (guaranteed at production test)
Low offset voltage: 50 μV maximum over specified CMRR range
Offset voltage drift: ±0.13 μV/°C typical, ±0.5 μV/°C maximum
Integrated guard buffer with 100 μV maximum offset
Low voltage noise density: 14 nV/√Hz at 10 kHz
Wide bandwidth: 2 MHz unity-gain crossover
Supply voltage: 4.5 V to 16 V (±2.25 V to ±8 V)
Operating temperature: −40°C to +125°C
Long-term offset voltage drift (10,000 hours): 0.5 μV typical
Temperature hysteresis: 1.5 μV typical

Application

Laboratory and analytical instrumentation: spectrophotometers, chromatographs, mass spectrometers, and potentiostatic and amperostatic coulometry
Instrumentation: picoammeters and coulombmeters
Transimpedance amplifier (TIA) for photodiodes, ion chambers, and working electrode measurements
High impedance buffering for chemical sensors and capacitive sensors
