MAX1147BCUP+

The MAX1147BCUP+ from Maxim Integrated Products is a multichannel, true-differential, serial, 14bit ADC in 20 pin TSSOP package. It features an internal track/hold (T/H), voltage reference and clock. The serial strobe output (SSTRB) allows convenient connection to digital signal processors. It uses an internal clock or an external serial-interface clock to perform SAR ADC. Includes an internal +2.500V reference. All devices accept an external reference from 1.5V to VDD. It provides a hardware shutdown and two software power-down modes. Using the software power-down modes allows the devices to be powered down between conversions. When powered down, accessing the serial interface automatically powers up the devices. The quick turn-on time allows power-down between all conversions. This technique reduces supply current to under 120µA for quick turn-on. Typical applications include portable data logging, data acquisition, medical instruments and process control.
