OPA445BM +BOM

Ideal for applications requiring precision voltage regulation and amplification

OPA445BM Information

Description

The Texas Instruments OPA445BM is a high-voltage FET-input operational amplifier designed for applications requiring wide power supply range, high slew rate, and low input bias current. It features a standard-pinout TO-99 package with a power supply range of ±10V to ±45V, making it suitable for industrial and instrumentation systems, power supply control in telecom equipment, motor control systems, high-speed data acquisition systems, and audio processing equipment. With a slew rate of 15V/µs and input bias current as low as 10pA, this amplifier is ideal for applications that require high accuracy and stability.

Features

According to the product information, the features of the OPA445BM are:

  • Wide power supply range: ±10V to ±45V
  • High slew rate: 15V/μs
  • Low input bias current: 10pA
  • Standard-pinout in TO-99, DIP, SO-8 PowerPAD, and SO-8 surface-mount packages

These features make the OPA445BM suitable for applications such as test equipment, high-voltage regulators, power amplifiers, data acquisition, signal conditioning, audio processing, and piezo drivers.
