The AD7933/AD7934 feature four analog input channels with a channel sequencer that allows a preprogrammed selection of channels to be sequentially converted. These parts can accept either single-ended, fully differential, or pseudo differential analog inputs.
The conversion process and data acquisition are controlled using standard control inputs that allow for easy interfacing to microprocessors and DSPs. The input signal is sampled on the falling edge of CONVST, and the conversion is also initiated at this point.
The AD7933/AD7934 has an accurate on-chip 2.5 V reference that is used as the reference source for the analog-to-digital conversion. Alternatively, this pin can be overdriven to provide an external reference.
These parts use advanced design techniques to achieve very low power dissipation at high throughput rates. They also feature flexible power management options. An on-chip control register allows the user to set up different operating conditions, including analog input range and configuration, output coding, power management, and channel sequencing.
Product Highlights
- High throughput with low power consumption.
- Four analog inputs with a channel sequencer.
- Accurate on-chip 2.5 V reference.
- Single-ended, pseudo differential or fully differential analog inputs that are software selectable.
- Single-supply operation with VDRIVE function. The VDRIVE function allows the parallel interface to connect directly to 3 V or 5 V processor systems independent of VDD.
- No pipeline delay.
- Accurate control of the sampling instant via a CONVST input and once-off conversion control.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
