CA3260EZ

Overview

The CA3260EZ is a dual operational amplifier from the CA3260 series, manufactured by Renesas Electronics Corporation. It features a BiMOS architecture combining PMOS input transistors with a CMOS output stage. The device operates on supply voltages ranging from 4V to 16V (or ±2V to ±8V split). Key electrical parameters include a unity gain crossover frequency of 4 MHz and a slew rate of 10 V/µs at ±7.5V. Input characteristics include an input resistance of 1.5 TΩ and an input current of 5 pA typical at 15V operation. The package is an 8-lead PDIP.

Feature Summary

• BiMOS technology integrates P-channel MOSFET inputs for high impedance and low bias current with a complementary symmetry CMOS output stage.

Applications

• Ground referenced single supply amplifiers
• Fast sample-hold amplifiers
• High input impedance wideband amplifiers

Procurement Notes

Verify that the specific ordering suffix matches the required RoHS compliance status and lead finish specifications. Confirm the package type corresponds to the through-hole wave solder processing requirements rather than reflow soldering applications. Ensure the manufacturer designation aligns with the intended supply chain source.

Selection Notes

Select this component when high input impedance and rail-to-rail output swing are required in a dual configuration. The PMOS input stage allows common mode voltage to extend below the negative supply rail, making it suitable for single-supply designs. Consider the CA3260A variant if superior input offset voltage characteristics are necessary compared to the standard CA3260.

Part Context

The CA3260EZ belongs to the CA3260 series of dual operational amplifiers. This series is characterized by its BiMOS construction, which merges the advantages of CMOS and bipolar technologies. The 'Z' suffix typically indicates Pb-free packaging compliant with RoHS standards, while the 'E' suffix denotes the extended temperature range capability.
