Description

The LMC660 is a CMOS Quad Operational Amplifier IC produced by Texas Instruments. This IC features four independent, high-gain, internally compensated operational amplifiers designed to operate with a wide supply voltage range while consuming very low power. The LMC660 is optimized for applications requiring low offset voltage, low input bias current, and high input impedance.

Features

  • Quad Operational Amplifiers: Contains four independent operational amplifiers in a single package.
  • Low Power Consumption: Designed for ultra-low power operation, consuming minimal current (ideal for battery-powered devices).
  • High Input Impedance: Suitable for high-impedance applications, ensuring minimal load on the preceding stage.
  • Low Input Bias Current: Ensures accurate operation with minimal current draw from the input signal source.
  • Low Offset Voltage: High precision with low voltage offset, improving the accuracy of signal processing.
  • Wide Supply Voltage Range: Can operate with a wide supply voltage, typically from 3V to 30V.
  • High Slew Rate: Offers sufficient bandwidth for many precision applications.
  • Rail-to-Rail Output: Capable of outputting voltages close to the supply rails, maximizing the usable output range.
  • CMOS Technology: Manufactured using CMOS technology, providing high input impedance and low power consumption.
  • SMD Package: Available in a Surface-Mount Device (SMD) package, making it suitable for compact and automated PCB designs.

Specifications

Electrical Characteristics
  • Operating Voltage Range: 3V to 30V (single supply) or ±1.5V to ±15V (dual supply).
  • Input Voltage Range: The input voltage can extend from the negative supply rail to the positive supply rail, making it suitable for rail-to-rail input applications.
  • Output Voltage Swing: Rail-to-Rail output, typically within a few millivolts of the rails depending on the load.
  • Input Bias Current: Very low input bias current, typically 1 pA at 25°C.
  • Input Offset Voltage: Very low offset voltage, typically 50 mV max.
  • Slew Rate: 0.3 V/µs, sufficient for many precision applications.
  • Gain Bandwidth Product: Typically 1 MHz, suitable for a wide range of signal processing tasks.
  • Power Consumption: Extremely low power consumption, typically 0.25 mA per amplifier (very low quiescent current).
  • Common-Mode Rejection Ratio (CMRR): Typically 90 dB, ensuring that common-mode signals are effectively rejected.
  • Power Supply Rejection Ratio (PSRR): Typically 90 dB, providing stable operation even with supply fluctuations.
  • Output Drive Capability: Capable of driving 2 kΩ loads to ground.
