ICL7612DMTV

Overview

The ICL7612DMTV is a single-channel CMOS operational amplifier manufactured by Analog Devices / Maxim Integrated. It features a gain-bandwidth product of 44 kHz and a slew rate of 16 mV/us. The input offset voltage is specified at 15 mV, with an input bias current of 50 pA. Operating supply voltages range from a minimum of 1 V to a maximum of 8 V for dual supplies, or 2 V to 16 V for single supplies. Quiescent current is 15 uA. The device offers a common-mode rejection ratio of 60 dB and an input voltage noise density of 100 nV/sqrt Hz. It is housed in an SOIC-8 surface-mount package and operates within a temperature range of 0 C to +70 C.

Feature Summary

• Ultra-low input bias current characteristic typical of CMOS technology
• Low power consumption suitable for battery-operated applications
• Rail-to-rail output capability swinging close to supply voltages

Applications

• Battery-powered instrumentation circuits
• High-impedance sensor signal conditioning
• Low-frequency analog filtering stages

Procurement Notes

Verify the manufacturer marking on the component body against Analog Devices or Maxim Integrated branding. Confirm the suffix 'MTV' corresponds to the specific tape-and-reel packaging variant. Ensure the part number matches the exact pinout and electrical specifications listed in the official datasheet before integration into production designs.

Selection Notes

Select this component when ultra-low input bias current is critical for high-impedance source applications. The low quiescent current makes it suitable for energy-constrained systems. Verify that the required bandwidth and slew rate meet the signal processing needs, as the device is optimized for low-frequency precision rather than high-speed amplification.

Part Context

This part belongs to the ICL761X family of monolithic CMOS operational amplifiers. The family combines ultra-low input current with low-power operation over a wide supply voltage range. Variants within the series offer pin-selectable quiescent currents to balance speed and power consumption requirements for different application scenarios.

Replacement Considerations

Check for direct replacements within the ICL7612 series such as ICL7612DCSA-T for identical performance in different packaging. Verify compatibility with other CMOS op-amps offering similar rail-to-rail outputs and low bias currents if sourcing from alternative manufacturers.
