CA3140MZ96

Overview

The CA3140MZ96 is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It features a single circuit with single-ended output in an 8-SOIC package. Key electrical parameters include a gain-bandwidth product of 4.5 MHz, a slew rate of 9V/µs, and an input bias current of 10 pA. The device operates within a supply voltage range of 4 V to 36 V and supports a continuous output current of 40 mA per channel. Input offset voltage is specified at 5 mV, and the operating temperature range extends from -55°C to 125°C.

Feature Summary

• BiMOS technology combining PMOS input transistors for high impedance and bipolar output stages
• Internal phase compensation ensuring stability in unity-gain follower configurations
• Zero-in adjustment terminals available for applications requiring input offset voltage nulling

Applications

• High-impedance sensor signal conditioning
• Photodiode preamplifier circuits
• Precision integrator designs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specifications may vary by production batch. Ensure proper ESD handling procedures during storage and assembly due to MOSFET input sensitivity. Validate package dimensions against PCB footprint requirements prior to procurement.

Selection Notes

Select this component when high input impedance and low bias current are critical design constraints. The BiMOS architecture offers superior speed compared to standard JFET inputs while maintaining high resistance. Consider the 8-SOIC package for surface-mount applications requiring compact form factors. Evaluate thermal management needs given the wide operating temperature range.

Part Context

This part belongs to the CA3140 series of BiMOS operational amplifiers originally developed by Radio Corporation of America (RCA). The series integrates high-voltage PMOS input stages with bipolar output drivers on a single monolithic chip. Renesas Electronics Corporation continues manufacturing variants under license, maintaining the original functional characteristics and pinout compatibility.
