THS4522IPWR - Dual Channel Differential Amplifier, TSSOP16

Description

The THS4522IPWR is a dual-channel, very low-power, fully differential amplifier with a common-mode input extending below the negative rail and a rail-to-rail output. Integrated voltage common-mode control (VOCM) enables direct connection to ADCs, eliminating the need for additional hardware. A 2.5 V to 5.5 V supply voltage range and a 20 µA power-down mode optimize power consumption for portable and high-density applications.
