Overview
The AD7767BRUZ-2-RL7 is a high-performance, single-channel, 24-bit oversampled successive approximation (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates with an output data rate of 32 kSPS and consumes 8.5 mW of power at this speed. The device features a dynamic range of 115.5 dB and a signal-to-noise ratio of 113.5 dB. It utilizes a differential input structure and requires a 2.5 V supply voltage with a 5 V reference. The component is housed in a 16-lead TSSOP package and supports serial communication interfaces.
Feature Summary
- Oversampled SAR architecture providing high AC and DC accuracy
- On-chip low-pass FIR filter with linear phase response for noise elimination
- Flexible interfacing options including synchronization and daisy-chain capabilities
Applications
- Low power PCI/USB data acquisition systems
- Vibration analysis instrumentation
- High precision medical acquisition
Procurement Notes
Verify the specific suffix -2-RL7 against official documentation to confirm the 32 kSPS decimation rate and reel packaging configuration. Ensure that the external reference voltage and logic drive levels match the datasheet requirements before finalizing procurement orders.
Selection Notes
Select the AD7767BRUZ-2-RL7 when a 32 kSPS output data rate and maximum dynamic range are required. Compare it against the AD7767-1 and AD7767 variants if higher sampling speeds or different power consumption profiles better suit the system design constraints.
Part Context
This component belongs to the AD7767 family of 24-bit ADCs from Analog Devices. The family includes variants optimized for different trade-offs between sampling speed and power consumption. The BRUZ-2 designation specifically identifies the version configured for the lowest power operation at 32 kSPS within the standard industrial temperature range.
Replacement Considerations
The AD7767BRUZ-1-RL7 offers 64 kSPS performance, while the AD7767BRUZ-RL7 provides 128 kSPS. These alternatives share the same package and interface but differ in decimation rates and power dissipation characteristics.
