- Ventron No:
- 3010888-AD7934BRUZ-6
- Description:
- IC ADC 12BIT 4CH 625KSPS 28TSSOP
- Datasheet:
- AD7934BRUZ-6
Description
The AD7934-6 is a 12-bit, high-speed, low-power, successive approximation (SAR) analog-to-digital converter (ADC). It operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 625 kSPS. The part contains a low noise, wide bandwidth, differential track-and-hold amplifier that handles input frequencies up to 50 MHz.
The AD7934-6 features four analog input channels with a channel sequencer that allows a preprogrammed selection of channels to be converted sequentially. This part can accept either single-ended, fully differential, or pseudo differential analog inputs. Data acquisition and conversion are controlled by standard control inputs that allow for easy interfacing to microprocessors and DSPs. The input signal is sampled on the falling edge of CONVST, which is also the point where the conversion is initiated.
The AD7934-6 has an accurate on-chip 2.5 V reference that can be used as the reference source for the analog-to-digital conversion. Alternatively, this pin can be overdriven to provide an external reference.
The AD7934-6 uses advanced design techniques to achieve very low power dissipation at high throughput rates. The part also features 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.
Features
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
No pipeline delay
Accurate control of the sampling instant via a CONVST input and once-off conversion control
Applications
Data acquisition systems
Industrial control systems
Medical instrumentation
Test and measurement equipment
Battery-powered applications
