Overview
The ADA4830-2WBCPZ-R7 is a dual-channel high-speed difference amplifier from Analog Devices, designed for automotive vision and infotainment systems. It integrates input short-to-battery protection up to 18 V and features an output flag for diagnostics. The device operates on a single supply of 2.9 V to 5.5 V with a quiescent current of 6.8 mA per channel. Key electrical parameters include a gain bandwidth product of 84 MHz, a slew rate of 250 V/µs, and a fixed differential gain of 0.50 V/V. It is housed in a space-saving 3 mm × 3 mm LFCSP package.
Feature Summary
- Integrates robust input overvoltage (short-to-battery) protection capable of withstanding voltages up to 18 V without external series capacitors.
- Includes a dedicated short-to-battery output flag pin that signals fault conditions via logic level changes for wire diagnostics.
- Provides high common-mode rejection and excellent video specifications, including low differential gain and phase errors.
- Features an enable/disable mode that allows the device to be powered down to minimize current consumption.
Applications
- Automotive vision systems
- Automotive infotainment
- Surveillance systems
Procurement Notes
Verify the specific suffix 'R7' indicates reel packaging when sourcing. Confirm the 'W' designation aligns with automotive qualification requirements for your target environment. Ensure the LFCSP-16 footprint matches your PCB layout constraints. Cross-reference the datasheet revision to confirm parameter consistency during procurement.
Selection Notes
Select this component for applications requiring differential CVBS signal reception in noisy environments. The dual-channel configuration supports multiple camera inputs within a single package. Consider the fixed 0.50 V/V gain for compatibility with standard video decoders. Evaluate the thermal resistance characteristics if operating near maximum temperature limits.
Part Context
This part belongs to the ADA4830 family, which includes the single-channel ADA4830-1. The dual-channel variant shares identical electrical characteristics and protection features but offers two independent amplifiers in one package. The automotive grade version ensures reliability under harsh conditions typical of vehicle electronics.
Replacement Considerations
ADA4830-1WBCPZ-R7 serves as the single-channel equivalent within the same family.
FAQ
How does the device handle input overvoltage?
The device employs fast switching circuitry to clamp internal voltage nodes at a safe level when an input exceeds the specified threshold, protecting sensitive internal components.
What is the function of the STB pin?
The STB pin acts as a short-to-battery indicator output. It provides a logic low signal to indicate an overvoltage condition and a logic high for normal operation.
