com High-Voltage, Programmable Gain DIFFERENCE AMPLIFIER FEATURES q HIGH COMMON-MODE VOLTAGE: +40V at VS = +5V ±100V at VS = ±15V q DIFFERENTIAL GAIN = 0.
1V/V TO 100V/V: Set with External Resistors q LOW QUIESCENT CURRENT: 570µA q WIDE SUPPLY RANGE: Single Supply: 4.
5V to 36V Dual Supplies: ±2.
25V to ±18V q LOW GAIN ERROR: 0.
025% q HIGH CMR: 80dB q SO-8 PACKAGE DESCRIPTION The INA146 is a precision difference amplifier that can be used to accurately attenuate high differential voltages and reject high common-mode voltages for compatibility with common signal processing voltage levels.
High-voltage capability also affords inherent input protection.
The input common-mode range extends beyond both supply rails, making the INA146 well-suited for both single and dual supply applications.
On-chip precision resistors are laser-trimmed to achieve accurate gain and high common-mode rejection.
Excellent TCR tracking of these resistors assures continued high precision over temperature.
A 10:1 difference amplifier provides 0.
1V/V gain when the output amplifier is used as a unity-gain buffer.
In this configuration, input voltages up to ±100V can be measured.
Gains greater than 0.
1V/V can be set with an external resistor pair without affecting the common-mode input range.
The INA146 is available in the SO-8 surface-mount package specified for the extended industrial temperature range, –40°C to +85°C.
