EVALUATION KIT AVAILABLE MAX11335–MAX11340 500ksps, 12-/10-Bit, 4-/8-/16-Channel ADCs with Post-Mux External Signal Conditioning Access General Description Benefits and Features The MAX11335–MAX11340 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 MAX11335–MAX11340 provide external access to the output of the integrated mux and ADC input, to simplify conditioning. The MAX11335–MAX11340 include both internal and external clock modes. These devices 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 SampleSetK technology, a user-programmable analog input channel sequencer. The SampleSet approach provides greater sequencing flexibility for multichannel applications while alleviating significant microcontroller or DSP (controlling unit) communication overhead. External pins provide access to the output of the multiplexer and ADC inputs to simplify multichannel signal conditioning. The internal clock mode features an integrated FIFO allowing data to be sampled at high speeds and then held for readout at any time or at a lower clock rate. Internal averaging is also supported in internal clock mode improving SNR for noisy input signals. The devices feature analog input channels that can be configured to be single-ended inputs, fully differential pairs, or pseudodifferential inputs with respect to one common input. The MAX11335–MAX11340 operate from a 2.35V to 3.6V supply and consume only 4.2mW at 500ksps. The MAX11335–MAX11340 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 8MHz, 3-wire serial interface directly connects to SPI, QSPIK, and MICROWIREM devices without external logic. Excellent dynamic performance, low voltage, low power, ease of use, and small package size make these converters ideal for portable battery-powered data-acquisition applications, and for other applications that demand low power consumption and small space. The MAX11335–MAX11340 are available in 32-pin, 5mm x 5mm, TQFN packages and operate over the -40NC to +125NC temperature range.
