MAX186, MAX188 Low-Power, 8-Channel, Serial 12-Bit ADCs

The MAX186 MAX188 are 12-bit data-acquisition systems that combine an 8-channel multiplexer, high-bandwidth track/hold, and serial Interface together with high conversion speed and ultra-low power consumption. The devices operate with a single +5V supply or dual 5V supplies. The Analog inputs are software configurable for unipolar/bipolar and single-ended/differential 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. B 576 oth parts have a reference-buffer Amplifier that simplifies gain trim.
The MAX186 MAX188 provide a hard-wired active-low 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 conversion. Using this technique of powering down between conversions, supply current CAN be cut to under 10A at reduced sampling rates.
The MAX186 MAX188 are available in 20-pin DIP and SO packages, and in a shrink small-outline package (SSOP), that occupies 30% less area than an 8-pin DIP. For applications that call for a parallel Interface see the MAX180 MAX181 data sheet. For anti-aliasing Filters consult the MAX274 MAX275 data sheet.
