SLAS635A – APRIL 2009 – REVISED JUNE 2009 Dual Channel 14-/12-Bit, 250-/210-MSPS ADC With DDR LVDS and Parallel CMOS Outputs • Internal and External Reference Support • Maximum Sample Rate: 250 MSPS • 64-QFN Package (9 mm × 9 mm) • 14-Bit Resolution – ADS62P49/ADS62P48 ADS62PXX HIGH SPEED FAMILY • 12-Bit Resolution – ADS62P29/ADS62P28 250 MSPS 210 MSPS 200 MSPS • Total Power: 1.25 W at 250 MSPS 14-Bit Family ADS62P49 ADS62P48 • Double Data Rate (DDR) LVDS and Parallel 12-Bit Family ADS62P29 ADS62P28 CMOS Output Options 11-Bit Family ADS62C17 • Programmable Gain up to 6dB for SNR/SFDR Trade-Off • DC Offset Correction • 90dB Cross-Talk • Supports Input Clock Amplitude Down to 400 mVPP Differential The ADS62Px9/x8 is a family of dual channel 14-bit and 12-bit A/D converters with sampling rates up to 250 MSPS. It combines high dynamic performance and low power consumption in a compact 64 QFN package. This makes it well-suited for multi-carrier, wide band-width communications applications. The ADS62Px9/x8 has gain options that can be used to improve SFDR performance at lower full-scale input ranges. It includes a dc offset correction loop that can be used to cancel the ADC offset. Both DDR LVDS (Double Data Rate) and parallel CMOS digital output interfaces are available. It includes internal references while the traditional reference pins and associated decoupling capacitors have been eliminated. Nevertheless, the device can also be driven with an external reference. The device is specified over the industrial temperature range (–40°C to 85°C).
