ESCRIPTION
:
Maxwell Technologies’ 5102ALPRP is a 16-bit mono-
lithic CMOS analog-to-digital converter capable of 20
kHz throughput. 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 R

® 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.

1. Minimum resolution for which no missing codes are guaranteed over the specified temperature range.
2. Applies after calibration at any temperature within the specified temperature range.
3. Total drift over specified temperature range after calibration at power-up at 25°C.
4. Guaranteed by characterization (5102A die).
5. Wideband noise aliased into the baseband. Referred to the input.
6. Applied only in the track mode. When converting or calibrating, input capacitance will not exceed 30 pF.
7. Conversion time scales directly to the master clock speed. The times shown are for synchronous, internal loopback (FRN
mode). In PDT, RBT, and SSC modes, asynchronrous delay between the falling edge of HOLD and the start of conversion may
add to the apparent conversion time. This delay will not exceed 1 master clock cycle + 140 ns.
8. The 5102ALPRP requires 6 clock cycles of coarse charge, followed by a minimum of 5.625 µ s of fine charge. FRN mode
allows 9 clock cycles for fine charge which provides for the minimum 5.625 µ s with a 1.6 MHz clock; however, in PDT, RBT, or
SSC modes, at clock frequencies less than 1.6 MHz, fine charge may be less than 9 clock cycles.
9. Throughput is the sum of the acquisition and conversion times. It will vary in accordance with conditions affecting acquisition
and conversion times described above.
10.Typical value (measured).
11. All outputs unloaded. All inputs at VD+ or DGND.
12.Power consumption in the sleep mode applies with no master clock applied (CLKIN held high or low).
13.With 300 mV p-p, 1 kHz ripple applied to each supply separately in the bipolar mode. Rejection improves by 6 dB in the unipo-
lar mode to 90 dB.
