TI Introduces 16-Bit Analog-to-Digital Converter at 200 MSPS

Texas Instruments Incorporated (TI) has introduced the 16-bit, single-channel, 200 mega samples per second (MSPS) analog-to-digital converter (ADC) to provide faster speeds previously only available with lower resolution ADCs. The data converters enable new levels of performance in communications, test and measurement, and defense applications. Suited for wide-bandwidth, high-sensitivity applications, the 16-bit Model ADS5485 can achieve signal-to-noise ratio of 75 dBFS and spurious-free dynamic range of 87 dBc for 70 MHz input frequency. Single-channel unit eases analog front end design by incorporating fully differential input buffer, which provides constant input impedance over input frequency and eliminates kickback from ADC's track-and-hold structure to ensure consistent linearity of signal. The ADS5485 expands TI's ADS548x family of low-noise ADCs. The devices are available in a space-saving 9 x 9 mm, 64-pin QFN package and suggested resale pricing for each is listed below in 1000-piece quantities.
