CA3140MZ96S2705

Overview

The CA3140MZ96S2705 is a BiMOS operational amplifier featuring PMOS input and bipolar output stages. It operates on supply voltages from 4V to 36V (single or dual). Key electrical parameters include a gain-bandwidth product of 4.5MHz, a slew rate of 9V/µs, and an input bias current of 10pA typical at ±15V. The device offers high input impedance of 1.5TΩ and includes internal phase compensation for stable unity-gain operation.

Feature Summary

• Integrates gate-protected PMOS transistors with high-voltage bipolar transistors on a single monolithic chip.
• Provides very high input impedance and extremely low input bias current.
• Features built-in protection against damage from load terminal short circuits to either supply rail or ground.
• Includes dedicated terminals for input offset voltage nulling and supplementary external frequency compensation.

Applications

• Ground-referenced single supply amplifiers in automobile and portable instrumentation
• Sample and hold amplifiers
• Photocurrent instrumentation
• Peak detectors
• Active filters

Procurement Notes

Verify the specific suffix 'MZ96S2705' against official Renesas documentation to confirm package type, tape-and-reel specifications, and RoHS compliance status. Ensure the ordering information matches the required temperature range and packaging format before finalizing procurement.

Selection Notes

Select this component when high input impedance and low bias current are critical requirements. It serves as a direct replacement for industry standard 741 operational amplifiers in most applications while offering superior speed and input characteristics suitable for single-supply systems.

Part Context

FAQ

Can the CA3140 operate with a single power supply?

Yes, the CA3140 can operate with a single power supply down to 4V. The common mode input voltage range extends to 0.5V below the negative supply rail, making it suitable for ground-referenced single-supply applications.

How is the input offset voltage adjusted?

Input offset voltage can be nulled using the dedicated offset null terminals. A potentiometer is typically connected between the offset null pins, with its wiper connected to the negative supply rail.
