________________General Description
The MAX192 is a low-cost, 10-bit data-acquisition system
that combines an 8-channel multiplexer, high-bandwidth
track/hold, and serial interface with high conversion
speed and ultra-low power consumption. The device
operates with a single +5V supply. The analog inputs are
software configurable for single-ended and differential
(unipolar/bipolar) operation.
The 4-wire serial interface connects directly to SPI,
QSPI, and Microwire devices, without using external
logic. A serial strobe output allows direct connection to
TMS320 family digital signal processors. The MAX192
uses either the internal clock or an external serial-
interface clock to perform successive approximation A/D
conversions. The serial interface can operate beyond
4MHz when the internal clock is used. The MAX192 has
an internal 4.096V reference with a drift of ±30ppm typi-
cal. A reference-buffer amplifier simplifies gain trim and
two sub-LSBs reduce quantization errors.
The MAX192 provides a hardwired SHDN pin and two
software-selectable power-down modes. Accessing the
serial interface automatically powers up the device, and
the quick turn-on time allows the MAX192 to be shut
down between conversions. By powering down
between conversions, supply current can be cut to
under 10A at reduced sampling rates.
The MAX192 is available in 20-pin DIP and SO pack-
ages, and in a shrink-small-outline package (SSOP)
that occupies 30% less area than an 8-pin DIP. The
data format provides hardware and software compati-
bility with the MAX186/MAX188. For anti-aliasing filters,
consult the data sheets for the MAX291–MAX297.
