TI OPA137N/250

Общее назначение1 МГц

Overview

The OPA137N/250 is a FET-input Operational Amplifier, designed for low cost and miniature applications. Provides low input bias current (5pA), low quiescent current (220mA/channel) and high open-loop gain (94dB). Either single (+4.5 to +36V) or dual (±2.25 to ±18V) supplies can be used. The input common-mode voltage range includes the positive supply - suitable for many single-supply applications. Single, dual and quad versions have identical specifications for maximum design flexibility. OPA137N/250 operation amplifier is easy to use and free from phase inversion and overload problems found in some FET-input amplifiers. High performance, including linearity, is maintained as the amplifiers swing to their specified limits. In addition, the combination of high slew rate (3.5V/ms) and wide bandwidth (1MHz) provide fast settling time assuring good dynamic response. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.
