THS452x Differential Amplifiers

Texas Instruments THS452x Differential Amplifiers

Texas Instruments' THS452x family of fully differential op amps

Texas Instruments' THS4520 is a wideband, fully differential operational amplifier designed for 5 V data acquisition systems. It has very low noise at 2 nV/ load. The slew rate is 570 V/µs, and with a settling time of 7 ns to 0.1% (2 V step), it is ideal for data acquisition applications. It is designed for unity gain stability.  THS4520 Datasheet

The THS4521, THS4522, and THS4524 family of devices are very low-power, fully differential op amps with rail-to-rail output and an input common-mode range that includes the negative rail. These amplifiers are designed for low-power data acquisition systems and high-density applications where power dissipation is a critical parameter, and provide exceptional performance in audio applications.  THS4521/2/4 Datasheet
