The MAX1132/MAX1133 are 200ksps, 16-bit ADCs.
These serially interfaced ADCs connect directly to
SPI™, QSPI™, and MICROWIRE™ devices without
external logic. They combine an input scaling network,
internal track/hold, clock, a +4.096V reference, and
three general-purpose digital output pins (for external
multiplexer or PGA control) in a 20-pin SSOP package.
The excellent dynamic performance (SINAD ≥ 85dB),
high-speed (200ksps), and low power (7.5mA) of these
ADCs, make them ideal for applications such as indus-
trial process control, instrumentation, and medical
applications. The MAX1132 accepts input signals of 0
to +12V (unipolar) or ±12V (bipolar), while the
MAX1133 accepts input signals of 0 to +4.096V (unipo-
lar) or ±4.096V (bipolar). Operating from a single
+4.75V to +5.25V analog supply and a +4.75V to
+5.25V digital supply, power-down modes reduce
current consumption to 1mA at 10ksps and further
reduce supply current to less than 20µA at slower data
rates. A serial strobe output (SSTRB) allows direct con-
nection to the TMS320 family of digital signal proces-
sors. The MAX1132/MAX1133 user can select either the
internal clock, or an external serial-interface clock for
the ADC to perform analog-to-digital conversions.
The MAX1132/MAX1133 feature internal calibration cir-
cuitry to correct linearity and offset errors. On-demand
calibration allows the user to optimize performance.
Three user-programmable logic outputs are provided
for the control of an 8-channel mux or a PGA.
