MAX186/MAX188
Low-Power, 8-Channel,
Serial 12-Bit ADCs
General Description
The MAX186/MAX188 are 12-bit data-acquisition sys-
tems that combine an 8-channel multiplexer, high-
bandwidth track/hold, and serial interface together with
high conversion speed and ultra-low power consump-
tion. The devices operate with a single +5V supply or
dual ±5V supplies. The analog inputs are software con-
figurable for unipolar/bipolar and single-ended/differen-
tial operation.
The 4-wire serial interface directly connects to SPI,
QSPI™ and MICROWIRE® devices without external
logic. A serial strobe output allows direct connection to
TMS320 family digital signal processors. The
MAX186/MAX188 use 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 MAX186 has an internal 4.096V reference while the
MAX188 requires an external reference. Both parts have
a reference-buffer amplifier that simplifies gain trim .
The MAX186/MAX188 provide a hard-wired
SHDN
pin
and two software-selectable power-down modes.
Accessing the serial interface automatically powers up
the devices, and the quick turn-on time allows the
MAX186/MAX188 to be shut down between every con-
version. Using this technique of powering down
between conversions, supply current can be cut to
under 10µA at reduced sampling rates.
The MAX186/MAX188 are available in 20-pin PDIP and
SO packages, and in a shrink small-outline package
(SSOP), that occupies 30% less area than an 8-pin
PDIP. For applications that call for a parallel interface,
see the MAX180/MAX181 data sheet. For anti-aliasing
filters, consult the MAX274/MAX275 data sheet.
