TI THS4531 ADC driver

Texas Instruments Inc. is offering a fully differential analog-to-digital converter (ADC) driver that it claims 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 highlights:

  • Bandwidth of 36 MHz, slew rate of 220 V/us and fast settling time of 150 ns to 0.01 percent reduces data acquisition time for driving high sample rate converters. 
  • Power-down mode to 0.5 uA, quiescent current of 250 uA, and 2.5-V to 5-V supply operation allows battery-powered operation and flexible power supply selection.
  • 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 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. 

Pricing: Suggested retail price of US $1.10 in 1,000-unit quantities.

Availability: Today in 2-mm x 2-mm QFN, 3-mm x 5-mm MSOP and 5-mm x 6-mm SOIC package options.
