DESCRIPTION
The ADS852 is a high-dynamic range 14-bit, 65MHz
pipelined analog-to-digital converter. It includes a high-
bandwidth linear track/hold that gives excellent spurious
performance up to and beyond the Nyquist rate. This high-
bandwidth track/hold also has a low jitter of only 0.25pS
rms, leading to excellent SNR performance. The clock input
can accept a low level differential sine wave or square wave
signal down to 0.5Vp-p, further improving the SNR perfor-
mance. It also accepts a single-ended clock signal and has
flexible threshold levels.
The ADS852 has a 4Vp-p differential input range (2Vp-p x
2 inputs, +16dBm) for optimum signal-to-noise ratio. The
differential operation gives the lowest even-order harmonic
components. A lower input voltage of 3Vp-p or 2Vp-p can
also be selected using the internal references, further opti-
mizing SFDR. Alternatively, a single-ended input range can
be used by tying the IN input to the common-mode voltage
if desired.
The ADS852 also provides an over-range flag that indicates
when the input signal has exceeded the converter’s full-scale
range. This flag can also be used to reduce the gain of the
front end signal conditioning circuitry. It also employs
digital error correction techniques to provide excellent dif-
ferential linearity for demanding imaging applications. The
ADS852 is available in a small 48-lead TQFP package.
