MAX1020/MAX1022/MAX1057/MAX1058 19-3280 Rev 5 2/12 10-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports General Description Features The MAX1020/MAX1022/MAX1057/MAX1058 integrate a 10-Bit, 225ksps ADC Analog Multiplexer with True-Differential multichannel, 10-bit, analog-to-digital converter (ADC) and an octal, 10-bit, digital-to-analog converter (DAC) in a Track/Hold (T/H) 16 Single-Ended Channels or 8 Differential single IC. These devices also include a temperature sen- sor and configurable general-purpose I/O ports (GPIOs) Channels (Unipolar or Bipolar) (MAX1057/MAX1058) with a 25MHz SPI-/QSPI-/MICROWIRE -compatible 12 Single-Ended Channels or 6 Differential serial interface. The ADC is available in 8/12/16 input- Channels (Unipolar or Bipolar) (MAX1022) channel versions. The octal DAC outputs settle within 8 Single-Ended Channels or 4 Differential 2.0s, and the ADC has a 225ksps conversion rate. Channels (Unipolar or Bipolar) (MAX1020) All devices include an internal reference (2.5V or 4.096V) Excellent Accuracy: 0.5 LSB INL, 0.5 LSB DNL providing a well-regulated, low-noise reference for both 10-Bit, Octal, 2s Settling DAC the ADC and DAC.

The low glitch Internal 1C Accurate Temperature Sensor energy (4nVs) and low digital feedthrough (0.5nVs) of On-Chip FIFO Capable of Storing 16 ADC the integrated octal DACs make these devices ideal for Conversion Results and One Temperature Result digital control of fast-response closed-loop systems. On-Chip Channel-Scan Mode and Internal The devices are guaranteed to operate with a supply volt- Data-Averaging Features age from +2.7V to +3.6V (MAX1057) and from +4.75V to +5.25V (MAX1020/MAX1022/MAX1058). The devices Analog Single-Supply Operation consume 2.5mA at 225ksps throughput, only 22A at +2.7V to +3.6V or +4.75V to +5.25V 1ksps throughput, and under 0.2A in the shutdown Digital Supply: 2.7V to V AVDD mode. The MAX1057/MAX1058 feature 12 GPIOs, while 25MHz, SPI/QSPI/MICROWIRE Serial Interface the MAX1020 offers four GPIOs that can be configured as inputs or outputs. AutoShutdown Between Conversions The MAX1057/MAX1058 are available in 48-pin thin QFN Low-Power ADC packages. The MAX1020/MAX1022 are available in 36- 2.5mA at 225ksps pin thin QFN packages. All devices are specified over the 22A at 1ksps -40C to +85C temperature range. 0.2A at Shutdown Low-Power DAC: 1.5mA Applications Evaluation Kit Available (Order MAX1258EVKIT) Controls for Optical Components Base-Station Control Loops QSPI is a trademark of Motorola, Inc.
