AD7927BRU Product Details
The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily 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 AD7927BRU uses advanced design techniques to achieve very low power dissipation at maximum throughput rates. At maximum throughput rates, the AD7927BRU consumes 1.2 mA maximum with 3 V supplies; with 5 V supplies, the current consumption is 1.5 mA maximum.
Through the configuration of the control register, the analog input range for the part can be selected as 0 V to REFIN or 0 V to 2 × REFIN, with either straight binary or twos complement output coding. The AD7927BRU features eight single-ended analog inputs with a channel sequencer to allow a preprogrammed selection of channels to be converted sequentially.
The conversion time for the AD7927BRU is determined by the SCLK frequency, as this is also used as the master clock to control the conversion. The conversion time may be as short as 800 ns with a 20 MHz SCLK.
- High Throughput with Low Power Consumption. The AD7927BRU offers up to 200 kSPS throughput rates. At the maximum throughput rate with 3 V supplies, the AD7927BRU dissipates 3.6 mW of power maximum.
- Eight Single-Ended Inputs with a Channel Sequencer. A consecutive sequence of channels can be selected on which the ADC cycles and converts.
- Single-Supply Operation with VDRIVE Function. The AD7927BRU operates from a single 2.7 V to 5.25 V supply. The VDRIVE function allows the serial interface to connect directly to either 3 V or 5 V processor systems independent of AVDD.
- 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. The part also features various shutdown modes to maximize power efficiency at lower throughput rates. Current consumption is 0.5 μA maxi-mum when in full shutdown.
- No Pipeline Delay. The part features a standard successive approximation ADC with a CS input pin, which allows for accurate control of each sampling instant.
