Description

The CA3140 is a high-speed BiMOS op-amp, combining the advantages of bipolar transistors for high-speed performance and CMOS transistors for low input bias current and low offset voltage. This hybrid design makes it well-suited for a wide range of applications, including audio, signal conditioning, and precision measurement systems.

Features

  • BiMOS Technology: Combines the high-speed characteristics of bipolar transistors with the low power and low offset properties of CMOS transistors.
  • Low Input Bias Current: The CMOS input stage ensures minimal bias current, making it ideal for high-impedance applications.
  • Low Input Offset Voltage: Provides high accuracy in low-voltage signal applications.
  • High Slew Rate: Offers fast response times to rapidly changing input signals.
  • Wide Bandwidth: Provides a good frequency response for general-purpose analog signal processing.
  • Low Power Consumption: Efficient design for applications where power consumption is critical.

Specifications

  • Supply Voltage: Typically ±3V to ±18V (or 6V to 36V single supply), making it compatible with a wide range of power sources.
  • Input Offset Voltage: Typically ±3mV, with a maximum value of ±10mV, ensuring accurate signal amplification.
  • Input Bias Current: Typically 50nA at 25°C, which is quite low and allows use in high-impedance circuits.
  • Output Voltage Swing: Typically ±10V when supplied with ±15V, ensuring the output can swing nearly to the supply rails.
  • Slew Rate: Typically 0.5V/µs, suitable for a variety of audio and signal processing applications where fast response is required.
  • Common-Mode Rejection Ratio (CMRR): Typically 90 dB, ensuring excellent rejection of common-mode signals.
  • Power Consumption: Low power consumption, typically 2mA, making it suitable for battery-operated and low-power systems.
  • Bandwidth: Typically 1 MHz at a gain of 1, making it suitable for a wide range of signal processing applications.
