The LM224DR is a quad operational amplifier (op-amp) in a SOIC-14 package, designed for low-power, single or split-supply applications. Here are the key details based on available information:

Specifications:

• Type: Quad, high-gain, frequency-compensated operational amplifier
• Number of Amplifiers: 4
• Bandwidth (Gain Bandwidth Product): 1.2 MHz
• Slew Rate: 0.5 V/µs
• Supply Voltage Range:
  • Single supply: 3V to 30V
  • Split supply: ±1.5V to ±15V
• Input Bias Current: Low (suitable for low-power applications)
• Common-Mode Input Voltage Range: Includes ground, allowing direct sensing near ground
• Supply Current: ~0.8 mA (typical, independent of supply voltage)
• Package: SOIC-14 (SMD, 14 pins)
• Operating Temperature: 0°C to 70°C (some variants, like LM224DR2G, support -25°C to +85°C)
