The MAX11166 16-bit, 500ksps, SAR ADC offers excellent AC and DC performance with true bipolar input range, small size, and internal reference. The MAX11166 measures a ±5V (10VP-P) input range while operating from a single 5V supply. A patented charge-pump architecture allows direct sampling of high-impedance sources. The MAX11166 integrates an optional internal reference and buffer, saving additional cost and space.

These ADCs achieve 92.9dB SNR and -103dB THD. The MAX11166 guarantees 16-bit no-missing codes and ±0.4 LSB INL (typ).

The MAX11166 communicates using an SPI-compatible serial interface at 2.5V, 3V, 3.3V, or 5V logic. The serial interface can be used to daisy-chain multiple ADCs in parallel for multichannel applications and provides a busy indicator option for simplified system synchronization and timing.

The MAX11166 is offered in 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.

Product Detail

The MAX11166 evaluation system (EV system) includes a mother board and daughter board to evaluate the MAX11166 16-bit ADC. The EV system includes a simple graphical user interface (GUI) for exercising the features of the IC. This GUI is compatible with Windows XP®-, Windows Vista®-, and Windows® 7. The EV system GUI allows different sample sizes, adjustable sampling rates, internal or external reference options, and graphing software that includes the following representations of the sampled signals: time domain, frequency domain, histogram, and single conversion.
The EV system is made up of the MAXPRECADCMB mother board with an on-board Altera FPGA and the daughter board for evaluating the IC. The mother board plugs into the PC through a high-speed USB link to send SPI commands through the GUI. The mother board accepts a 5V supply. The daughter board accepts ±15V supplies.
The daughter board comes installed with a MAX11166ETC+ in a 12-pin TDFN-EP package.
