2-channel ADC

2 February 2011 Analogue, Mixed Signal, LSI

Maxim’s new MAX11645 is claimed to be the industry’s smallest 2-channel ADC.

This 12-bit I²C device includes an internal reference in a tiny 1,9 x 2,2 mm wafer-level package (WLP). A 4 x 3 bump array with 0,5 mm pitch facilitates layout on four-layer PCBs, while a low 0,64 mm height makes it suitable for designs laying components out on both sides of the PCB.

The ADC minimises both external component count and total solution size, only requiring a 0,1 μF ceramic bypass capacitor on the supply voltage input. Combining a compact footprint with low power dissipation (18 μW at 1 ms conversion times), the MAX11645 is well suited for applications ranging from energy-harvesting sensors to portable consumer electronics, to point-of-load monitoring (voltage, current and temperature) in networking and computer systems.

The IC is capable of sample rates up to 94 Ksps. By taking advantage of this high sample rate, multiple channels can be converted in a short period of time. This capability allows the device to spend more time in shutdown mode, further reducing total system power consumption. The MAX11645 operates from a single 2,7 V to 3,6 V supply and includes a 2,048 V internal reference. It offers up to 70 dB SINAD, ±1 LSB (max) INL and DNL error, plus 0,3 ppm/°C gain-error temperature drift. Input signals in the 0 to VREF (unipolar) or ±VREF/2 (bipolar) range can be resolved with true 12-bit accuracy.

For applications that require less than 12-bit resolution, the MAX11647 is a pin-compatible 10-bit version of the MAX11645. The ICs are offered in 12-bump WLP and 8-pin μMAX packages, and are guaranteed over the -40°C to +85°C temperature range.
