AD7829: 3 V/5 V, 2 MSPS, 8-Bit, 1-/4-/8-Channel Sampling ADCs

The AD7822/AD7825/AD7829 are high speed, 1-, 4-, and 8-channel, microprocessor-compatible, 8-bit analog-to-digital converters with a maximum throughput of 2 MSPS. The AD7822/AD7825/AD7829 contain an on-chip reference of 2.5 V (2% tolerance); a track-and-hold amplifier; a 420 ns, 8-bit half-flash ADC; and a high speed parallel interface. The converters can operate from a single 3 V ± 10% and 5 V ± 10% supply.

AD7829 特点

• 8-bit half-flash ADC with 420 ns conversion time
• 1, 4 and 8 Single-Ended Analog Input Channels Available with Input Offset Adjust
• On-Chip Track-and-Hold
• SNR Performance Given for Input Frequencies Up to 10 MHz
• Automatic Power-Down at the End of Conversion
• On-Chip Reference (2.5 V)
• Wide Operating Supply Range 3 V ± 10% and 5 V ± 10%
• Input Ranges:
  0 V to 2 V p-p, VDD = 3 V ± 10%
  0 V to 2.5 V p-p, VDD = 5 V ± 10%
• Flexible Parallel Interface with EOC Pulse to Allow Stand-Alone Operation
