DESCRIPTION
The ADS58H43 is a high-linearity, quad-channel, 14-
bit, 250-MSPS analog-to-digital converter (ADC). The
four ADC channels are separated into two blocks with
two ADCs each. Each block can be individually
configured into three different operating modes. One
operating mode includes the implementation of the
SNRBoost^3G+ signal processing technology to provide
high signal-to-noise ratio (SNR) in a band up to
90 MHz wide with only 11-bit resolution. Designed for
low power consumption and high spurious-free
dynamic range (SFDR), the ADC has low-noise
performance and outstanding SFDR over a large
input frequency range.
