On-chip self-calibration achieves nonlin- earity of ±0.001% of FS and guarantees 16-bit no miss- ing codes over the entire specified temperature range. Offset and full-scale errors are minimized during the cali- bration cycle, eliminating the need for external trimming. The 5102ALP each consist of a 2-channel input multi- plexer, DAC, conversion and calibration microcontroller, clock generator, comparator, and serial communications port. The inherent sampling architecture of the device eliminates the need for an external track and hold ampli- fier. Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the micro- circuit package. It eliminates the need for box shielding while improving the TID performance in most space environments. This product is available with screening up to Maxwell Technologies self-defined Class K. 01.17.05 REV 3 (858) 503-3300 Fax: (858) 503-3301 - www.maxwell.com All data sheets are subject to change without notice 1 ©2005 Maxwell Technologies Inc.

Minimum CLKIN period is 0.625 µ s is FRN mode (20 kHz sample rate). 2. External loading capacitors are required to allow the crystal to oscillate. Maximum crystal frequency is 1.6 MHz in FRN mode (20 kHz sample rate). 3. With a 2.0 MHz crystal, two 33 pF loading capacitors and a 10 MW parallel resistor. 4. Guaranteed by initial characterization (5102A die). 5. These times are for FRN mode. 6. These times are for PDT and RBT modes. 01.17.05 REV 3 All data sheets are subject to change without notice 5 ©2005 Maxwell Technologies Inc.
