General Description The MAX1102/MAX1103/MAX1104 CODECs provide both an 8-bit analog-to-digital converter (ADC) and an 8-bit digital-to-analog converter (DAC) with a 4-wire logic interface. The MAX1102/MAX1103 include an onboard +2V/+4V reference, providing a well-regulat- ed, low noise reference for both the ADC and DAC. The MAX1104 offers ratiometric conversion, with the reference internally connected to VDD. The MAX1102/MAX1103/MAX1104 are low-cost, low- power CODECs for use with microcontrollers (µCs). They allow for greater flexibility when selecting a µC. Less expensive µCs without onboard converters can be used while maintaining overall system performance. The MAX1102 operates from a single +2.7V to +3.6V supply, the MAX1103 operates from a +4.5V to +5.5V supply, and the MAX1104 operates from a +2.7V to +5.5V supply. The MAX1102/MAX1103 incorporate a VDD monitor in addition to AIN for power supply moni- toring. All devices feature a low 18µA standby mode, where both data converters are disabled while the ref- erence remains active, and three shutdown modes: ADC disabled, DAC disabled, and complete shutdown (1µA). A quick 10µs wake-up time allows the MAX1102/MAX1103/MAX1104 to cycle in and out of shutdown even during short-duration idle times. The MAX1102/MAX1103/MAX1104 are available in a space-saving 8-pin µMAX package. ________________________Applications Analog I/O for Microcontrollers Analog System Signal Supervision Voice Recording and Playback Features o 8-Bit ADC ±1LSB INL Built-In Track-and-Hold 48dB of SINAD o 8-Bit DAC ±1LSB INL 55dB of SFDR o Internal Conversion Clock o Single-Supply Operation +2.7V to +3.6V (MAX1102) +4.5V to +5.5V (MAX1103) +2.7V to +5.5V (MAX1104) o Low Power Consumption 0.5mA at 25ksps 1µA Shutdown Mode o 6MHz 4-Wire SPI™, QSPI™, and MICROWIRE™ Compatible Interface o Compact 8-Pin µMAX Package o Internal Voltage Reference +2V: MAX1102 +4V: MAX1103 o Power-Supply Monitor (MAX1102/MAX1103) o Rail-to-Rail® DAC Output Buffer 8-Bit CODECs ________________________________________________________________ Maxim Integrated Products 1 1 2 3 4 8 7 6 5 DIN DOUT SCLK CS OUT AIN GND VDD MAX1102 MAX1103 MAX1104 µMAX TOP VIEW Pin Configuration SCLK SERIAL INTERFACE AND CONTROL LOGIC ADC DAC LATCH T/H AIN VDD/2 AOUT VOLTAGE REFERENCE DIN DOUT MAX1102 MAX1103 MAX1104 GND VDD DAC CS Functional Diagram 19-1873; Rev 0; 12/00 Ordering Information PART TEMP.
