MAX1220
Overview
The MAX1220-MAX1223/MAX1257/MAX1258 integrate a 12-bit, multichannel, analog-to-digital converter (ADC), and a 12-bit, octal, digital-to-analog converter (DAC) in a single IC. These devices also include a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface.
- s) and low digital feedthrough (0.5nV
- s) of the integrated octal DACs make these devices ideal for digital control of fast-response closed-loop systems. The devices are guaranteed to operate with a supply voltage from +2.7V to +3.6V (MAX1221/MAX1223/MAX1257) and from +4.75V to +5.25V (MAX1220/MAX1222/ MAX1258). These devices consume 2.5mA at 300ksps throughput, only 22µA at 1ksp throughput, and under 0.2µA in the shutdown mode. The MAX1257/MAX1258 feature 12 GPIOs, while the MAX1220/MAX1221 offer 4 GPIOs that can be configured as inputs or outputs. The MAX1220-MAX1223 are available in 36-pin thin QFN packages. The MAX1257/MAX1258 are available in 48-pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range. Features
- 12-Bit, 300ksps ADC Analog Multiplexer with True-Differential Track/Hold (T/H) 16 Single-Ended Chan
