Two-channel ADC for energy-harvesting sensors
The MAX11645 two-channel ADC is suited for applications ranging from energy-harvesting sensors to portable consumer electronics and point-of-load monitoring in networking and computer systems.
A 4 x 3 bump array with 0.5mm pitch facilitates layout on four-layer PCBs, while a 0.64mm height makes it suitable for designs laying components out on both sides of the PCB.
This ADC minimises external component count and total solution size, only requiring a 0.1microfarad ceramic bypass capacitor on the supply voltage input.
It combines a compact footprint with power dissipation of 18mW at 1ms conversion times.
The MAX11645 is capable of sample rates up to 94ksps, meaning that 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 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/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.
Offering pin- and software-compatible two-/four-/eight-/12-channel, 8-/10-/12-bit ADCs enables designers to easily trade off space, performance and cost on platform designs.
These ADCs also include internal references, FIFOs and selectable scan modes.
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 eight-pin Micromax packages, and are guaranteed over the -40 to 85C extended temperature range.
Evaluation kits are available for the four-, eight- and 12-channel versions (MAX11613/MAX11615/MAX11617) of these ADCs.
