TI ADC driver provides industry’s highest performance-to-power ratio by 8x

Key features and benefits of the THS4531:

• 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.

Tools and support
The THS4531DGKEVM evaluation module is available to speed evaluation of the THS4531. It can be ordered today for $149. PSPICE and TINA-TI Spice models are also available, along with a TINA-TI reference design.

Availability, packaging and pricing
The THS4531 is available today in 2-mm x 2-mm QFN, 3-mm x 5-mm MSOP and 5-mm x 6-mm SOIC package options for a suggested retail price of US$1.10 in 1,000-unit quantities.
