GENERAL DESCRIPTION  
The AD79461 is a 14-bit, charge redistribution, successive  
approximation, analog-to-digital converter (ADC) that operates  
from a single 5 V power supply, VDD. It contains a low power,  
high speed, 14-bit sampling ADC with no missing codes, an  
internal conversion clock, and a versatile serial interface port.  
The part also contains a low noise, wide bandwidth, short  
aperture delay track-and-hold circuit. On the CNV rising edge,  
it samples an analog input IN+ between 0 V to REF with respect  
to a ground sense IN−. The reference voltage, REF, is applied  
externally and can be set up to the supply voltage.  
SPI-/QSPI™-/MICROWIRE™-/DSP-compatible  
Daisy-chain multiple ADCs and BUSY indicator  
Power dissipation  
3.3 mW at 5 V/100 kSPS  
3.3 µW at 5 V/100 SPS  
Standby current: 1 nA  
10-lead MSOP (MSOP-8 size) and  
3 mm × 3 mm LFCSP (SOT-23 size)  
Pin-for-pin compatible with the 16-bit AD7686  
APPLICATIONS  
Its power scales linearly with throughput.  
Battery-powered equipment  
Data acquisition  
Instrumentation  
Medical instruments  
Process control  
The SPI-compatible serial interface also features the ability,  
using the SDI input, to daisy-chain several ADCs on a single,  
3-wire bus, or it provides an optional BUSY indicator. It is  
compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate  
supply VIO.  
The AD7946 is housed in a 10-lead MSOP or a 10-lead LFCSP  
with operation specified from −40°C to +85°C.
