MAX9920 - Current-Sense Amplifiers

Download the MAX9920 datasheet PDF. This datasheet also covers the MAX9918 variant, as both devices belong to the same current-sense amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX9918/MAX9919/MAX9920 are single-supply, high-accuracy current-sense amplifiers with a high input common-mode range that extends from -20V to +75V.

Key Features

  • fixed gains of 45V/V (MAX9919F) and 90V/V (MAX9919N). The MAX9918/MAX9919/MAX9920 operate as unidirectional amplifiers when VREFIN = GND and as bidirectional amplifiers when VREFIN = VCC/2. The MAX9920 attenuates the input signal by a factor of 4 at the input level-shifting stage allowing the device to sense voltages up to 200mV (unidirectional operation) or ±100mV (bidirectional operation). The MAX9918/MAX9919/MAX9920 operate with a single 5V supply voltage, are fully specified over the -40°C t.

MAX9918/MAX9919/MAX9920 -20V to +75V Input Range, Precision Uni-/Bidirectional, Current-Sense Amplifiers General Description The MAX9918/MAX9919/MAX9920 are single-supply, high-accuracy current-sense amplifiers with a high input common-mode range that extends from -20V to +75V. These amplifiers are well suited for current monitoring of inductive loads such as motors and solenoids, where common-mode voltages can become negative due to inductive kickback, reverse-battery conditions, or transient events. The MAX9918/MAX9920 feature adjustable gain set by an external resistive-divider network. The MAX9919 features fixed gains of 45V/V (MAX9919F) and 90V/V (MAX9919N).
