GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD7910/AD79201 are, respectively, 10-bit and 12-bit, high  
speed, low power, successive approximation ADCs. The parts  
operate from a single 2.35 V to 5.25 V power supply and feature  
throughput rates up to 250 kSPS. The parts contain a low noise,  
wide bandwidth track-and-hold amplifier that can handle input  
frequencies in excess of 13 MHz.  
1. 10-/12-bit ADCs in SC70 and MSOP packages.  
2. Low power consumption.  
3. Flexible power/serial clock speed management. The  
conversion rate is determined by the serial clock, allowing  
the conversion time to be reduced through the serial clock  
speed increase. This allows the average power consumption  
to be reduced when power-down mode is used while not  
converting. The part also features a power-down mode to  
maximize power efficiency at lower throughput rates.  
Current consumption is 1 μA maximum and 50 nA typically  
when in power-down mode.  
The conversion process and data acquisition are controlled  
CS  
using  
and the serial clock, allowing the devices to interface  
with microprocessors or DSPs. The input signal is sampled on  
the falling edge of  
point. There are no pipeline delays associated with the part.  
CS  
and the conversion is initiated at this  
The AD7910/AD7920 use advanced design techniques to  
achieve very low power dissipation at high throughput rates.  
4. Reference derived from the power supply.  
5. No pipeline delay. The parts feature a standard successive  
approximation ADC with accurate control of the sampling  
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 to VDD. The conversion rate  
is determined by the SCLK.
