ADC provides more

TI ADC driver provides industry’s highest performance-to-power ratio by 8x.
Texas Instruments Incorporated (TI) has redefined the low-power amplifier market with the introduction of a fully differential analogue-to-digital converter (ADC) driver that provides more than eight times the performance-to-power ratio of similar devices.
The THS4531 fully differential amplifier uses only 250 uA of quiescent current while providing 36 MHz of bandwidth to support the high-performance, ultra-low power needs of portable and high-density systems, such as flow meters and portable medical devices.
Key features include bandwidth of 36 MHz, slew rate of 220 V/us and fast settling time of 150 ns to 0.01% reduces data acquisition time for driving high sample rate converters.
In addition, it’s power-down mode to 0.5 uA, quiescent current of 250 uA, and 2.5V to 5V supply operation allows battery-powered operation and flexible power supply selection.
Furthermore, flexible negative-rail input common mode and rail-to-rail output enables simplified interface design with single-ended, ground-based signal sources and differential successive approximation register (SAR) and delta-sigma ADCs.
Measuring only 2 mm x 2 mm, it is the industry’s smallest, high-speed, fully differential amplifier, making it suitable for use in high-density applications.
The THS4531 is available now in 2 mm x 2 mm QFN, 3 mm x 5 mm MSOP and 5 mm x 6 mm SOIC package options.
