ADC1283 - 12-bit SAR ADC

The ADC1283 is a low-power, eight-channel pure CMOS 12-bit analog-to-digital converter specified for conversion from 50 ksps to 200 ksps, tested at 200 ksps (3.2 MHz clock frequency).

The architecture is based on a successive-approximation register with an internal track-and-hold cell.

• 50 ksps to 200 ksps conversion rate.
• 8-to-1-channel input MUX.
• 2.7 V to 5.5 V digital I/Os supply voltage.
• 2.7 V to 5.5 V analog supply voltage.
• DNL (AVCC = DVCC = 5 V): +/- 0.9 LSB maximum.
• INL (AVCC = DVCC = 5 V): +/- 1.2 LSB maximum.
• Very low consumption: Pd = 3.2 mW typical @ 5 V supply.
• Power-down mode.
• Temperature range: -40 °C to 125 °C.
• 4-wire SPI serial digital interface.
• TSSOP-16 package.
