Dual, High-Side, Current-Sense Amplifiers and  
Drive Amplifiers  
General Description  
Features  
The MAX1350–MAX1357 offer two programmable high-  
side current-sense amplifiers and two drive amplifiers  
integrated in a single package.  
High-Side Current-Sense Amplifier with Gain of  
2 or 10  
1ꢀ Current-Sense Aꢁꢁuraꢁc  
The current-sense amplifiers have a 5V to 32V common-  
mode input range and provide a voltage output that is a  
multiple of the sense voltage. The common-mode input  
range is independent of supply voltage. An external  
sense resistor determines the range of current monitored  
by a current-sense amplifier. Gains of 2 or 10 are avail-  
able with a typical input-referred offset voltage of zero or  
3mV. The 3mV offset option is ideal for applications where  
offset nulling is required.  
Wide 5V to 32V Common-Mode Voltage Range—  
Independent of Supplc Voltage  
Adjustable Low Noise 0 to 5V or 0 to 10V Output  
Voltage Ranges with 10mA Gate ꢂriꢃe  
ꢂriꢃe Amplifier Features Fast Clamp to Ground  
The drive amplifiers provide up to 10mA of output cur-  
rent capability and a high output capacitive load toler-  
ance. Output transients are limited to 100mV during  
power-up and power-down events. The drive amplifiers  
feature a digitally controllable fast output clamp to  
ground. The drive amplifier outputs are current limited  
and are offered with gains of 2 or 4.

The drive amplifiers draw approximately 4.75mA, while  
the current-sense amplifiers draw approximately 250µA  
with full-scale sense inputs. In shutdown mode, the total  
supply current reduces to less than 1µA.  
The MAX1350–MAX1357 are available in a 20-pin  
TSSOP package and operate over the extended (-40°C  
to +85°C) temperature range.  
*Future product—contact factory for availability.  
**For parts that operate over a wider temperature range, contact  
factory for availability.
