The MAX1127 quad, 12-bit analog-to-digital converter
(ADC) features fully differential inputs, a pipelined
architecture, and digital error correction. This ADC is
optimized for low-power, high-dynamic performance for
medical imaging, communications, and instrumentation
applications. The MAX1127 operates from a 1.7V to
1.9V single supply and consumes only 563mW while
delivering a 69.6dB signal-to-noise ratio (SNR) at a
19.3MHz input frequency. In addition to low operating
power, the MAX1127 features a 675µA power-down
mode for idle periods.
An internal 1.24V precision bandgap reference sets the
ADC's full-scale range. A flexible reference structure
allows the use of an external reference for applications
requiring increased accuracy or a different input voltage
range.
A single-ended clock controls the conversion process.
An internal duty-cycle equalizer allows for wide variations
in input-clock duty cycle. An on-chip phaselocked
loop (PLL) generates the high-speed serial
low-voltage differential signaling (LVDS) clock.
The MAX1127 provides serial LVDS outputs for data,
clock, and frame alignment signals. The output data is
presented in two's complement or binary format.
Refer to the MAX1126 data sheet for a pin-compatible
40Msps version of the MAX1127.
The MAX1127 is available in a small, 10mm x 10mm x
0.9mm, 68-pin QFN package with exposed paddle and
is specified for the extended industrial (-40°C to +85°C)
temperature range.
