Overview
The ADA4830-1WBCPZ-R7 is a single-channel, high-speed difference amplifier from Analog Devices, designed for automotive-grade applications. It integrates input short-to-battery protection up to 18 V and features an 84 MHz bandwidth with a 250 V/µs slew rate. Operating on a single supply of 2.9 V to 5.5 V, it consumes 6.8 mA per channel. The device provides a fixed gain of 0.50 V/V and includes an enable pin and a short-to-battery output flag. It is housed in a compact 3 mm × 3 mm LFCSP package.
Feature Summary
- Integrates robust input overvoltage protection capable of withstanding short-to-battery conditions up to 18 V without external components.
- Provides a dedicated logic output flag to indicate fault conditions when input voltage exceeds defined thresholds.
- Features a wide input common-mode voltage range allowing direct connection to remote video sources.
- Includes an enable function that allows the device to be disabled to minimize power consumption.
Applications
- Automotive vision systems
- Automotive infotainment
- Surveillance systems
Procurement Notes
Verify the specific suffix 'W' indicates automotive qualification and 'R7' denotes reel packaging. Confirm the 'BCPZ' designation corresponds to the 8-lead LFCSP package variant. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Cross-reference the datasheet revision C specifications against current manufacturing data sheets to validate performance parameters.
Selection Notes
Select this component for applications requiring differential or pseudo-differential CVBS video signal reception in noisy environments. It is suitable for designs needing direct connection to cameras without series capacitors due to integrated protection. Consider the fixed 0.50 V/V gain for compatibility with standard video decoders. Evaluate the space-saving LFCSP package for constrained PCB layouts.
Part Context
This part belongs to the ADA4830 family of monolithic high-speed difference amplifiers. The ADA4830-1 represents the single-channel version, while the ADA4830-2 offers dual channels. Both variants share similar electrical characteristics and protection features but differ in package lead count and physical dimensions.
Replacement Considerations
The ADA4830-1BCPZ-R7 is the commercial grade equivalent. The ADA4830-2WBCPZ-R7 serves as the dual-channel alternative within the same automotive qualified series.
