MAX1132/33x ADCs

MAX1132/33x ADCs

Maxim's MAX11321-28 and MAX11335-40 are 10-/12-bit with external reference and 500 kHz, full-linear-bandwidth, high-speed, low-power, serial-output successive approximation register (SAR) analog-to-digital converters (ADCs). The MAX series devices provide external access to the output of the integrated mux and ADC input, to simplify conditioning. They also include both internal and external clock modes, and feature 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 SampleSet™ technology, a user-programmable analog input channel sequencer.

Features
  • Analog multiplexer with true differential track/hold
    • 4-/8-/16-channel single-ended
    • 4-/8-/12-channel fully-differential pairs
    • 4-/8-/15-channel pseudo-differential relative to a common input
  • 16-entry First-In/First-Out (FIFO)
  • Scan modes, internal averaging, and internal clock
  • Sample set: user-defined channel sequence with maximum length of 256
  • Input pins: any combination of single-ended, differential and pseudo-differential pairs allowed
