DESCRIPTION
The ADS62P19 is part of a family of dual-channel,
11-bit, analog-to-digital converters (ADCs) with
sampling rates up to 250 MSPS. The device
combines high dynamic performance and low power
consumption in a compact QFN-64 package. This
functionality makes the device well-suited for multi-
carrier, wide-bandwidth communication applications.
The ADS62P19 has gain options that can be used to
improve spurious-free dynamic range (SFDR)
performance at lower full-scale input ranges. The
device includes a dc offset correction loop that can be
used to cancel ADC offset. Both double data rate
(DDR) low-voltage differential signaling (LVDS) and
parallel complementary metal oxide semiconductor
(CMOS) digital output interfaces are available.
Although the device includes internal references, the
traditional reference pins and associated decoupling
capacitors are 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).
