Description
ADS58B18 ADS58B19 www.ti.com SBAS487D * NOVEMBER 2009 * REVISED JANUARY 2011 11-Bit, 200MSPS/9-Bit, 250MSPS, Ultralow-Power ADCs wit.
The ADS58B18/B19 are members of the ultralow power ADS4xxx analog-to-digital converter (ADC) family that features integrated analog buffers and SNRBoo.
Features
* 1
* 23 ADS58B18: 11-Bit, 200MSPS
* ADS58B19: 9-Bit, 250MSPS
* Integrated High-Impedance Analog Input
Buffer
* Ultralow Power:
* Analog Power: 258mW at 200MSPS
* I/O Power: 69mW (DDR LVDS, low LVDS
swing)
* High Dynamic Performance:
* ADS
Applications
* such as PA linearization. The ADS58B18 uses TI-proprietary SNRBoost technology that can be used to overcome SNR limitation as a result of quantization noise for bandwidths less than Nyquist (fS/2). Both devices have gain options that can be used to improve SFDR performance at lower full-scale input
