Overview
19-4009; Rev 1; 3/08 KIT ATION EVALU E L B AVAILA 10-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports General Description The MAX1021/MAX1043 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and a 10-bit, digital-toanalog converter (DAC) in a single IC.
The devices also include a temperature sensor and configurable generalpurpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/ MICROWIRE™-compatible serial interface.
The ADC is available in an eight input-channel version.
The DAC outputs settle within 2.
0µs, and the ADC has a 225ksps conversion rate.
All devices include an internal reference (2.
5V) to provide a well-regulated, low-noise reference for both the ADC and DAC.
Programmable reference modes for the ADC and DAC allow the use of an internal reference, an external reference, or a combination of both.
Features such as an internal ±1°C accurate temperature sensor, FIFO, scan modes, programmable internal or external clock modes, data averaging, and AutoShutdown™ allow users to minimize both power consumption and processor requirements.
The low glitch energy (4nV•s) and low digital feedthrough (0.
5nV•s) of the integrated 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 +5.
25V.
They consume 2.
5mA at 225ksps throughput, only 22µA at 1ksps throughput, and under 0.
2µA in the shutdown mode.
The MAX1021/ MAX1043 offer four GPIOs that can be configured as inputs or outputs.
The MAX1021/MAX1043 are available in 36-pin thin QFN packages.
These devices are specified over the -40°C to +85°C temperature range.
