The MAX1169 is a low-power, 16-bit successive-approximation analog-to-digital converter (ADC). The device features automatic power-down, an on-chip 4MHz clock, a +4.096V internal reference, and an I²C-compatible 2-wire serial interface capable of both fast and high-speed modes.

The MAX1169 operates from a single supply and consumes 5mW at the maximum conversion rate of 58.6ksps. AutoShutdown™ powers down the device between conversions, reducing supply current to less than 50µA at a 1ksps throughput rate. The option of a separate digital supply voltage allows direct interfacing with +2.7V to +5.5V digital logic.

The MAX1169 performs a unipolar conversion on its single analog input using its internal 4MHz clock. The full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1V to VAVDD.

The four address select inputs (ADD0 to ADD3) allow up to 16 MAX1169 devices on the same bus.

The MAX1169 is packaged in a 14-pin TSSOP and operates over an extended temperature range. Refer to the MAX1069 data sheet for a 14-bit device in a pin-compatible package.

Product Details

The MAX1169 evaluation system (EV system) is a complete high-speed I²C-compatible 16-bit data-acquisition system consisting of a MAX1169 evaluation kit (EV kit), Maxim 68HC16MODULE-DIP microcontroller (µC) module, USBTO232, and a HS I²C-compatible module.

The HSI2CMOD has a proven HS-mode I²C-compatible interface that supports the MAX1169's maximum 2-wire serial clock frequency of 1.7MHz. This solution is implemented on this module by using an Altera EPM3256AQC208-10-programmable logic device (PLD) and a DI2CM core from Digital Core Design.

Order the complete EV system (MAX1169EVC16) for a comprehensive evaluation of the MAX1169 using a personal computer (PC). Order the EV kit (MAX1169EVKIT) separately to evaluate the MAX1169 with a user-supplied HS/fast/standard- mode I²C-compatible interface.

To evaluate the MAX1169A_UD or MAX1169B_UD, request a free sample of the MAX1169A_UD or MAX1169B_UD when ordering the MAX1169 EV kit.
