Overview
The ADM4073HWRJZ-REEL7 is a low-cost, high-side current-sense amplifier with a fixed gain of 100 V/V. It operates on a supply voltage range of 3 V to 28 V and supports a common-mode input range from 2 V to 28 V. The device features a typical bandwidth of 1.6 MHz and a maximum supply current of 1.2 mA at 28 V. It provides full-scale accuracy within ±5.0% across the operating temperature range of −40°C to +125°C. Packaged in a 6-lead SOT-23, it offers pin-to-pin compatibility with the MAX4073.
Feature Summary
- Fixed internal gain of 100 V/V eliminates external resistor requirements for signal scaling.
- High common-mode rejection ratio ensures accurate sensing independent of supply voltage fluctuations.
- Wide bandwidth supports integration into fast battery-charger control loops.
- Operates without ground path interruption, suitable for rechargeable battery systems.
Applications
- Cell phones
- PDAs
- Notebook computers
- Portable, battery-powered systems
- Smart battery packs and chargers
Procurement Notes
Verify the specific suffix WRJZ-REEL7 against the manufacturer's ordering guide to confirm RoHS compliance and reel packaging specifications. Ensure the design utilizes the correct gain variant (H) for the required output voltage scaling. Confirm that the application circuit respects the absolute maximum ratings for differential input voltage and supply connections to prevent permanent damage.
Selection Notes
Select this component when a fixed 100 V/V gain is required for high-side current monitoring in portable electronics. It is appropriate for applications needing wide common-mode voltage coverage up to 28 V. Consider the 6-lead SOT-23 package size for space-constrained designs. Verify that the load impedance connected to the output does not exceed the internal output resistance limits to maintain accuracy.
Part Context
This part belongs to the ADM4073 family of low-cost, voltage-output, high-side current-sense amplifiers. The H suffix denotes the 100 V/V gain version, distinct from the T (20 V/V) and F (50 V/V) variants. All models share identical pinouts and thermal characteristics, facilitating direct substitution within the same series based on gain requirements.
Replacement Considerations
The datasheet specifies pin-to-pin compatibility with the Maxim Integrated MAX4073. Designers may substitute this part with the MAX4073 provided the gain and electrical specifications align with the system requirements.
