EVALUATION KIT AVAILABLE  
MAX186/MAX188  
Low-Power, 8-Channel,  
Serial 12-Bit ADCs  
General Description  
____________________________Features  
o 8-Channel Single-Ended or 4-Channel  
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.  
Differential Inputs  
o Single +5V or 5V Operation  
o Low Power: 1.5mA (Operating Mode)  
2µA (Power-Down Mode)  
o Internal Track/Hold, 133kHz Sampling Rate  
o Internal 4.096V Reference (MAX186)  
o SPI-/QSPI-/MICROWIRE-/TMS320-Compatible  
The 4-wire serial interface directly connects to SPI,  
4-Wire Serial Interface  
®
QSPI™ and MICROWIRE devices without external  
o Software-Configurable Unipolar or Bipolar Inputs  
o 20-Pin PDIP, SO, SSOP Packages  
o Evaluation Kit Available  
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 .  
20 SSOP  
Dice*  
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.

Ordering Information continued on last page.  
†Parts are offered in grades A, B, C and D (grades defined in  
Electrical Characteristics). When ordering, please specify grade.  
Contact factory for availability of A-grade in SSOP package.  
*Dice are specified at +25°C, DC parameters only.  
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.
