MAX1246, MAX1247 +2.7V, Low-Power, 4-Channel, Serial 12-Bit ADCs In QSOP-16

The MAX1246 MAX1247 12-bit data-acquisition systems combine a 4-channel multiplexer, high-bandwidth track/hold, and serial Interface with high conversion speed and low power consumption. The MAX1246 operates from a single +2.7V to +3.6V supply; the MAX1247 operates from a single +2.7V to +5.25V supply. Both devices' Analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation.
The 4-wire serial Interface connects directly to SPI/QSPI and MICROWIRE devices without external Logic A serial strobe outp 58c ut allows direct connection to TMS320-family digital signal processors. The MAX1246 MAX1247 use either the internal Clock or an external serial-interface Clock to perform successive-approximation Analog-to-digital conversions.
The MAX1246 has an internal 2.5V reference, while the MAX1247 requires an external reference. Both parts have a reference-buffer Amplifier with a 1.5% voltage-adjustment range. These devices provide a hard-wired SHDN-bar pin and a software-selectable power-down, and CAN be programmed to automatically shut down at the end of a conversion. Accessing the serial Interface automatically powers up the MAX1246 MAX1247 and the quick turn-on time allows them to be shut down between all conversions. This technique CAN cut supply current to under 60A at reduced sampling rates. The MAX1246 MAX1247 are available in a 16-pin DIP and a small QSOP that occupies the same board area as an 8-pin SO.
For 8-channel versions of these devices, see the MAX146 MAX147 data sheet.
