INA156

SPECIFICATIONS: VS = +2.7V to +5.5V

Boldface limits apply over the specified temperature range, TA = –55°C to +125°C

At TA = +25°C, RL = 10kΩ connected to VS/2. RG pins open (G = 10), and Ref = VS /2, unless otherwise noted.

NOTES: (1) For further information, refer to typical performance curves on common-mode input range. (2) Operation beyond (V+) – 1.8V (max) results in reduced common-mode

rejection. See discussion and Figure 6 in the text of this data sheet. (3) Does not include error and TCR of additional optional gain-setting resistor in series with RG, if used.
