概述

Description

CA3130EZ is a BiMOS operational amplifier (an MOSFET-input op-amp with a bipolar output stage). It combines very high input impedance with decent output drive, useful for single‑supply amplification of high‑impedance signals.
Key features (typical):
- MOS input pair for extremely low input bias current
- Wide supply range: typically 5–16 V (single or dual supply)
- Unity-gain stability with an external compensation capacitor
- Output can swing toward the rails under light load
- Input common‑mode range includes the negative rail
Notes:
- “EZ” denotes a specific package/variant of the CA3130 family (check the datasheet for exact package type and electrical limits).
- For exact parameters (GBW, offset, bias current, output swing, PSRR), consult the CA3130EZ datasheet.
Typical uses:
- High-impedance buffer/preamp
- Active filters and integrators
- Sensor interfaces and ADC front-ends
- Instrumentation front-ends requiring low bias current

Features

Key features of CA3130EZ:
- BiMOS operational amplifier with MOSFET input and bipolar output
- Very high input impedance and ultra-low input bias current (great for high-impedance sources)
- Wide supply range: supports single-supply (5–16 V) and dual supplies
- Input common-mode range includes the negative rail; output can swing close to rails under light loads
- External compensation capacitor required to set frequency response (gain); suitable for a wide range of closed-loop gains
- Moderate bandwidth and slew rate for precision amplification, buffering, and integrators
- Low input offset and drift for accurate amplification with high-impedance sensors
Note: Check datasheet for exact supply limits, compensation capacitor values, and rail-to-rail specifics for your operating conditions.

Package

CA3130EZ is an 8-pin package. It’s available in PDIP-8 and SO-8 (surface-mount) variants; check the datasheet for the exact option you need.

Pinout

- Pin count: 8 pins (DIP-8/SOIC-8)
- Function: CA3130EZ is a BiMOS operational amplifier with a MOS input stage and bipolar output stage, intended for general-purpose amplification (high input impedance; standard op-amp inputs, output, supply, and offset-null pins).

Manufacturer

- Manufacturer: Intersil (now part of Renesas Electronics).
- What kind of company: A global semiconductor company specializing in analog and mixed-signal integrated circuits (e.g., op-amps, power-management ICs).

Application

CA3130EZ is a BiMOS op-amp with MOS input and bipolar output, offering very high input impedance and single-supply operation. Common applications: high-impedance buffer/voltage follower; transimpedance/preamplifier for photodiodes and sensors; active filters and integrators; signal conditioning for pH, thermocouples, photodiodes, strain gauges; analog front ends for ADCs; peak detectors and sample/hold circuits in portable instrumentation.
