Ultra-Low-Power, Octal, 12-Bit, 50Msps,
1.8V ADC with Serial LVDS Outputs
General Description
The MAX19527 is an octal, 12-bit analog-to-digital
converter (ADC), optimized for the low-power and
high-dynamic performance requirements of medical
imaging instrumentation and digital communications
applications. The device operates from a single 1.8V
supply and consumes 440mW (55mW per channel),
while providing a 69dBFS signal-to-noise ratio (SNR) at
a 5.3MHz input frequency. In addition to low operating
power, the device features programmable power man-
agement for idle states and reduced-channel operation.
An internal 1.25V precision bandgap reference sets the
full-scale range of the ADC to 1.5VP-P. A flexible refer-
ence structure allows the use of an external reference
for applications requiring greater gain accuracy or a
different input voltage range. A programmable common-
mode voltage reference output is provided to enable
DC-coupled input applications.
Various adjustments and feature selections are avail-
able through programmable registers that are accessed
through the 3-wire serial peripheral interface (SPIK).
A flexible clock input circuit allows for a single-ended,
logic-level clock or a differential clock signal. An on-chip
PLL generates the multiplied (6x) clock required for
the serial LVDS digital outputs. The serial LVDS output
provides programmable test patterns for data timing
alignment and output drivers with programmable current
drive and programmable internal termination.
The device is available in a small, 10mm x 10mm x
1.2mm, 144-lead thin chip ball grid array (CTBGA) pack-
age and is specified for the extended industrial (-40NC to
+85NC) temperature range.
