Product Introduction

Overview

The LM324DR2, produced by onsemi, is a part of the LM324 series of low-cost, quad operational amplifiers. These amplifiers are designed for single supply applications and offer several distinct advantages over standard operational amplifier types. They can operate at supply voltages ranging from 3.0 V to 32 V, with quiescent currents significantly lower than those of the MC1741. The LM324 series is known for its true differential input stage and the ability to include the negative supply within the common mode input range, eliminating the need for external biasing components in many applications.

Key Specifications

Parameter Value Conditions

Quiescent Current About one-fifth of MC1741 per amplifier
Input Offset Voltage ±3 mV (LM324), ±2 mV (LM324B) VCC = 5.0 V, VEE = GND, TA = 25°C
Input Bias Current 50 nA maximum Across –40°C to 125°C
Common Mode Rejection Ratio (CMRR) 70 dB to 85 dB RS ≤ 10 kΩ
Power Supply Rejection Ratio (PSRR) 65 dB to 100 dB
Operating Temperature Range 0°C to +70°C (LM324DR2)
Package Type SOIC-14 (Pb-Free)

Key Features

  • True Differential Input Stage: Allows for true differential input signals.
  • Single Supply Operation: Can operate from a single supply voltage as low as 3.0 V or as high as 32 V.
  • Short Circuited Protected Outputs: Outputs are protected against short circuits.
  • Low Input Offset Voltage: Low input offset voltage of ±3 mV (LM324) or ±2 mV (LM324B).
  • ESD Rating: 2 kV (HBM), 1.5 kV (CDM) for B versions.
  • Integrated RF and EMI Filter: For improved noise rejection in B versions.

Applications

  • Merchant Network and Server Power Supply Units
  • Multi-function Printers
  • Power Supplies and Mobile Chargers
  • Desktop PC and Motherboard
  • Indoor and Outdoor Air Conditioners
  • Washers, Dryers, and Refrigerators
