It allows a • Pin-Compatible with ADS62P49 high-resolution, 14-bit output for a limited time • Variable Output Resolution followed by a low-resolution mode with a minimum of – High Resolution Burst Mode with 14-Bit 8x longer time. It is pin-compatible to the ADS62P49 Output: 73 dB SNR at Low IF, and ADS62C17 dual ADCs. 70.5 dB SNR at 170 MHz The ADS62PF49 has gain options that can be used – Low Resolution with 9-Bit 250 MSPS or to improve SFDR performance at lower full-scale 11-Bit 125 MSPS input ranges. It includes a dc offset correction loop • Double Data Rate (DDR) LVDS Output that can be used to cancel the analog-to-digital conversion (ADC) offset. • Programmable Gain up to 6 dB for SNR/SFDR Trade-off It includes internal references while the traditional • 90-dB Cross-Talk reference pins and associated decoupling capacitors • Power Consumption of 1.25 W have been eliminated. The device is specified over the industrial temperature range ( –40°C to 85°C). • 64-Pin QFN Package (9 mm × 9 mm) Table 1.
