Texas Instruments Introduces THS4531A and THS4532 Differential Amplifiers

Texas Instruments single-channel THS4531A and dual-channel THS4532 differential amplifiers

Texas Instruments introduced the single-channel THS4531A and dual-channel THS4532 differential amplifiers. The THS4531A is available now in 8-pin SOIC, 8-pin VSOP, and 10-pin QFN package options. It is priced at $1.21 in 1,000-unit quantities. The THS4532 is available now in a 16-pin TSSOP. It is priced at $1.85 in 1,000 unit quantities. The devices are ideal for test and measurement equipment, and digital and ultrasonic water flow meters.

Compared to the nearest competitor, the TI THS4531A and THS4532 feature seven times the bandwidth with one-fourth of the input referred noise while also reducing power consumption by 80%. The devices are designed for low-power data acquisition systems and high-density applications where power consumption and dissipation is critical.
