MAX40016

4-Decade Current Sense Ampliﬁer

with Integrated Current Sense Element

General Description

Beneﬁts and Features

● Integrated Current Sense Element Saves The Space

The MAX40016 is a very wide range current sense amplifier

(CSA) with internal sense element that senses from less

than 300µA to greater than 3A current range. The 4-decade

sensed current functions with 1% (typical) gain error and

offers three, multiplexed programmable output ranges in

order to interface with 12-bit ADCs. Having an integrated

sense element has the extra advantage that the entire

current measuring path can be factory-trimmed, saving the

user from having to calibrate independent sense resistors

and CSAs. The MAX40016 (WLP package) drops a typical

of 60mV at 3A from the voltage input to load output.

and Cost of Expensive Precision Sense Resistors

● 4-Decade Measurement Range

• Maintains Accuracy from < 300µA to > 3A

● Withstands Overloads to 4A

● Low Voltage Drop Across Sense Element

• 60mV (Active Mode, 3A Load, WLP Package)

• 35mV (Low Power Mode, 3A Load, WLP Package)

● Three Multiplexed Scaling Resistor Outputs Allow

Full Dynamic Range while Interfaced to 12-bit ADCs

The MAX40016's integrated current-sensing element

saves the space and cost of an external high-power,

precision current sense resistor. The MAX40016 is offered

in an ultra-tiny, 1.98mm x 1.31mm, 15-bump wafer-

level package (WLP), further reducing board space. The

MAX40016 is also available in a 4mm x 4mm 16-pin

TQFN package.

● +2.5V to +5.5V Input Supply Voltage Range

● Low Power Mode Reduces Supply Current to 10µA

Max

● Space-Saving

• Tiny 1.98mm x 1.3mm, 15-Bump WLP

• 4mm x 4mm 16-Pin TQFN

The MAX40016 operates with a supply voltage from 2.5V

to 5.5V. The device features a low-power mode in which

the current-sensing element remains on, but the outputs

are turned off to reduce the total supply current below

10µA (max).

● -40°C to +125°C Operating Temperature Range

Ordering Information appears at end of data sheet.

The MAX40016 also includes a committed on-board

amplifier with an internal gain of 1.5V/V. The MAX40016

operates over the -40°C to +125°C temperature range.

Applications

● Mobile Devices

● RF Power Monitoring

● Portable Instruments
