Speed is calculated for 5-V with a 2-V reference
(5.5 V to 3 V, I-temperature and C-temperature: 2 MSPS at 10 bit, 3 MSPS at 8 bit, 7 MSPS at 4 bit;
3 V to 2.7 V, C-temperature: 2 MSPS at 10 bit, 2.5 MSPS at 8 bit, 7 MSPS at 4 bit;
3 V to 2.7 V, I-temperature: 1.6 MSPS at 10 bit, 2.5 MSPS at 8 bit, 7 MSPS at 4 bit).
Higher throughput is possible when the linearity requirement is relaxed.
Dual interrupt mode is available to 8-bit or 10-bit resolution and single-ended input type.
§ Throughput from single selected channel.
Combined throughputs from a pair of selected channels.
RD-Strobe
Mono Interrupt Mode: 0 RD-Delay
Mono Continuous Mode : 1 RD-Delay
Dual Continuous Mode : 2~3 RD-Delay
Dual Interrupt Mode: 0~1 RD-Delay
