MAX11328
Description
The MAX11321–MAX11328 are 12-/10-bit with external reference and 500kHz, full-linear-bandwidth, high-speed, low-power, serial-output successive approximation register (SAR) analog-to-digital converters (ADCs). The MAX11321–MAX11328 provide external access to the output of the integrated mux and ADC input, to simplify conditioning.
Key Features
- scan mode in both internal and external clock modes
- The internal clock mode features internal averaging to increase SNR
- The external clock mode features the SampleSetK technology, a user-programmable analog input channel sequencer
- External pins provide access to the output of the multiplexer and ADC inputs to simplify multichannel signal conditioning
- Internal averaging is also supported in internal clock mode improving SNR for noisy input signals
- The MAX11321–MAX11328 operate from a 2.35V to 3.6V supply and consume only 5.4mW at 1Msps
- The MAX11321–MAX11328 include AutoShutdownK, fast wake-up, and a high-speed 3-wire serial interface
- The devices feature full power-down mode for optimal power management
- The 48MHz, 3-wire serial interface directly connects to SPI, QSPIK, and MICROWIREM devices without external logic
- The MAX11321–MAX11328 are available in 32-pin, 5mm x 5mm, TQFN packages and operate over the -40NC to +125NC temperature range
