Product Description

Product Details
The AD7466/AD7467/AD7468 are 12-/10-/8-bit, high speed, low power, successive approximation analog-to-digital converters (ADCs), respectively. The parts operate from a single 1.6 V to 3.6 V power supply and feature throughput rates up to 200 kSPS with low power dissipation. The parts contain a low noise, wide bandwidth track-and-hold amplifier, which can handle input frequencies in excess of 3 MHz.
The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS, and the conversion is also initiated at this point. There are no pipeline delays associated with the part.
The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus, the analog input range for the part is 0 V to VDD. The conversion rate is determined by the SCLK.
**Product Highlights**
1. Specified for supply voltages of 1.6 V to 3.6 V
2. 12-, 10-, and 8-bit ADCs in SOT-23 and MSOP packages
3. High throughput rate with low power consumption. Power consumption in normal mode of operation at 100 kSPS and 3 V is 0.9 mW maximum
4. Flexible power/serial clock speed management. The conversion rate is determined by the serial clock, allowing the conversion time to be reduced through increases in the serial clock speed. Automatic power-down after conversion allows the average power consumption to be reduced when in power-down. Current consumption is 0.1 μA maximum and 8 nA typically when in power-down
5. Reference derived from the power supply
6. No pipeline delay
7. The part features a standard successive approximation ADC with accurate control of conversions via a CS input
**Applications**
Battery-powered systems
Medical instruments
Remote data acquisition
Isolated data acquisition
