The Burr-Brown OPA2137 FET-input operational amplifiers are designed for low input bias current (5pA), low quiescent currrent (220μA/channel), and high open-loop gain (94dB). Either single (+4.5V 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. The OPA2137 op amps are 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/μs) and wide bandwidth (1MHz) provide fast settling time assuring good dynamic response.
