CA3130MZ

Overview

The CA3130MZ is a single-channel general-purpose operational amplifier from the Renesas Electronics CA3130 series, housed in an 8-pin SOIC surface-mount package. It features a BiMOS architecture with MOSFET input and CMOS output stages. Key electrical parameters include a gain-bandwidth product of 50 kHz to 15 MHz, a slew rate of 30 V/µs, and an input bias current as low as 2 pA to 30 pA. The device operates on supply voltages ranging from 6 V to 16 V or 2.5 V to 16 V, with an input offset voltage maximum of 15 mV. It supports a wide operating temperature range from -55°C to +125°C and delivers an output current of up to 45 mA.

Feature Summary

• BiMOS technology combining high-impedance P-channel MOSFET inputs with CMOS outputs for rail-to-rail swing capability
• Input common-mode voltage range extends below the negative supply rail, enabling single-supply operation
• CMOS output stage allows signal swing within 10mV of either power supply rail under high load impedance
• External phase compensation pin available for stability adjustment in specific circuit configurations

Applications

• Ground-referenced single-supply amplifiers
• Fast sample-and-hold circuits
• High-input-impedance comparators interfacing with digital CMOS logic
• Photodiode sensor amplifiers
• Peak detectors and precision rectifiers

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging variations. Ensure compliance with RoHS standards if required by the application. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference the part number with authorized distributors to validate authenticity and traceability.

Selection Notes

Select this component when high input impedance and low bias current are critical requirements. The BiMOS structure offers superior speed compared to standard JFET inputs while maintaining low noise characteristics. Consider the wide supply voltage range and single-supply compatibility for flexible system design. Evaluate the thermal performance within the specified -55°C to +125°C operating range for harsh environments.

Part Context

The CA3130 series represents a legacy BiMOS operational amplifier family originally developed by Harris and Intersil, now manufactured by Renesas Electronics. This series bridges the gap between bipolar and CMOS technologies, offering unique advantages in input impedance and output drive capabilities. The CA3130MZ variant specifically denotes the surface-mount SOIC-8 package version, widely used in industrial and commercial instrumentation.
