Features for the LM321

  • (VCC = 5 V, TA = 25°C.
    Typical values unless specified.)
  • Gain-Bandwidth Product 1 MHz
  • Low Supply Current 430 µA
  • Low Input Bias Current 45 nA
  • Wide Supply Voltage Range 3 V to 32 V
  • Stable With High Capacitive Loads
  • Single Version of LM324

Description for the LM321

The LM321 brings performance and economy to low power systems. With a high unity gain frequency and a specified 0.4-V/µs slew rate, the quiescent current is only 430-µA/amplifier (5 V). The input common mode range includes ground and therefore the device is able to operate in single supply applications as well as in dual supply applications. It is also capable of comfortably driving large capacitive loads.

The LM321 is available in the SOT-23 package. Overall the LM321 is a low power, wide supply range performance operational amplifier that can be designed into a wide range of applications at an economical price without sacrificing valuable board space.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
