MAX146, MAX147 +2.7V, Low-Power, 8-Channel, Serial 12-Bit ADCs

The MAX146 MAX147 12-bit data-acquisition systems combine an 8-channel multiplexer, high-bandwidth track/hold, and serial Interface with high conversion speed and low power consumption. The MAX146 operates from a single +2 643 .7V to +3.6V supply; the MAX147 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 output allows direct connection to TMS320-family digital signal processors. The MAX146 MAX147 use either the internal Clock or an external serial-interface Clock to perform successive-approximation Analog-to-digital conversions.
The MAX146 has an internal 2.5V reference, while the MAX147 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 MAX146 MAX147 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 MAX146 MAX147 are available in 20-pin DIP and SSOP packages.
For 4-channel versions of these devices, see the MAX1246 MAX1247 data sheet.
