Texas Instruments has introduced a fully differential analog-to-digital converter (ADC) driver that provides a very high performance-to-power ratio.
The THS4531 fully differential amplifier uses only 250 μA of quiescent current while providing 36 MHz of bandwidth to support the needs of portable and high-density systems, such as flow meters and portable medical devices.
Bandwidth of 36 MHz, slew rate of 220 V/μs and fast settling time of 150 ns to 0,01% reduce data acquisition time for driving high sample rate converters. A power-down mode to 0,5 μA, quiescent current of 250 μA, and 2,5 V to 5 V supply operation allows battery-powered operation and flexible power supply selection.
The IC provides 16-bit accuracy to drive ADCs, such as the ADS8317 and ADS1278, as well other DC-coupled applications. Flexible negative-rail input common mode and rail-to-rail output enable simplified interface design with single-ended, ground-based signal sources and differential successive approximation register (SAR) and delta-sigma ADCs.
