Two-Channel I2C ADC includes 2.048 V internal reference.
December 20, 2010 -
Housed in 1.9 x 2.2 mm WLP, 12-bit Model MAX11645 operates from 2.7-3.6 V supply and is capable of sample rates up to 94 ksps. Device offers up to 70 dB SINAD, ±1 LSB INL and DNL error, and 0.3 ppm/°C gain-error temperature drift. With 18 µW power dissipation at 1 ms conversion times, ADC is suited for energy-harvesting sensors, portable consumer electronics, and POL monitoring in networking and computer systems. A 4 x 3 bump array with 0.5 mm pitch facilitates layout on 4-layer PCBs.

Industry's Smallest 2-channel ADC Saves Space and Power
Expanding its industry-leading portfolio of I2C ADCs, Maxim announces a 2-channel, 12-bit ADC with internal reference in a space-saving 4mm2 WLP.
SUNNYVALE, CA - Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX11645, the industry's smallest 2-channel ADC. This 12-bit I2C ADC includes an internal reference in a tiny 1.9mm x 2.2mm wafer-level package (WLP). A 4 x 3 bump array with 0.5mm pitch facilitates layout on four-layer PCBs, while a slim 0.64mm height makes it perfect for designs laying components out on both sides of the PCB. This ADC minimizes both external component count and total solution size, only requiring a 0.1microfarad ceramic bypass capacitor on the supply voltage input. Combining a compact footprint with best-in-class power dissipation (18microwatts at 1ms 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 MAX11645 is capable of sample rates up to 94ksps--28x faster than the nearest competitor in a comparable solution size. By taking advantage of the ADC's 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 2.7V to 3.6V supply and includes a 2.048V internal reference. This 12-bit ADC offers up to 70dB SINAD, ±1 LSB (max) INL and DNL error, plus 0.3ppm/degrees Celsius 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.
The MAX11645 is the latest release in Maxim's extensive I2C ADC family. Offering pin- and software-compatible 2-/4-/8-/12-channel, 8-/10-/12-bit ADCs enables designers to easily trade off space, performance, and cost on platform designs. Uniquely, these ADCs also include internal references, FIFOs, and selectable scan modes. Refer to the selection table for the complete listing of MAX116xx I2C ADCs.
For applications that require less than 12-bit resolution, the MAX11647 is a pin-compatible 10-bit version of the MAX11645. The MAX11645/MAX11647 are offered in 12-bump WLP and 8-pin microMAX® packages, and are guaranteed over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Production quantities are available now. Pricing starts at $1.25 (1000-up, FOB USA). Evaluation kits are available for the 4-, 8-, and 12-channel versions (MAX11613/MAX11615/MAX11617) of these ADCs.
