ADA4062-4

The ADA4062-4 belongs to the ADA4062 family is ideal for various applications, including process controls, industrial and instrumentation equipment, active filtering, data conversion, buffering, and power control and monitoring. The ADA4062-2 and ADA4062-4 are dual and quad JFET-input amplifiers with industry-leading performance. The ADA4062-2 is available in lead-free, 8-lead SOIC, 8-lead MSOP, and 10-lead LFCSP (1.6 mm * 1.3 mm * 0.55 mm)packages, while the ADA4062-4 is available in lead-free, 14-lead TSSOP and 16-lead LFCSP packages. They offer lower power, offset voltage, drift, and ultralow bias current. The ADA4062-2 B grade (SOIC package)features a typical low offset voltage of 0.5 mV, an offset drift of 5 V/°C, and a bias current of 2 pA. With a low supply current of 165 A per amplifier, they are well suited for lower power applications. The ADA4062 family is also specified for the extended industrial temperature range of -40°C to +125°C.

The features of ADA4062-4 can be summarized as (1)low input bias current: 50 pA maximum; (2)offset voltage 1.5 mV maximum for B grade (ADA4062-2 SOIC package)2.5 mV maximum for A grade; (3)offset voltage drift: 5 V/°C typical; (4)slew rate: 3.3 V/s typical; (5)CMRR: 90 dB typical; (6)low supply current: 165 A typical; (7)high input impedance; (8)unity-gain stable; (9)±5 V to ±15 V dual-supply operation; (10)packaging 8-lead SOIC, 8-lead MSOP, 10-lead LFCSP, 14-lead TSSOP, and 16-lead LFCSP packages.

The absolute maximum ratings of ADA4062-4 are (1)supply voltage: ±18 V; (2)input voltage: ±VSY; (3)differential input voltage: ±VSY; (4)input current: ±10 mA; (5)output short-circuit duration to GND: indefinite; (6)storage temperature range: -65°C to +150°C; (7)operating temperature range: -40°C to +125°C; (8)junction temperature range: -65°C to +150°C; (9)lead temperature (soldering, 60 sec): 300°C.
