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.
