l
denotes specifications that apply over the full specified temperature range, otherwise specifications are at TA = 25°C. Unless noted otherwise, V+ = 5V, V– = 0V, V+IN1 = V2 = Mid-Supply, VSHDN = V+, RL = OPEN, RF = SHORT, RG = OPEN. VS is defined as (V+ – V–). VOUTCM is defined as (VOUT1 + VOUT2)/2. VOUTDIFF is defined as (VOUT1 – VOUT2). See Figure 1. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS

Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
VOS2 is measured as the total output common mode voltage offset may cause permanent damage to the device. Exposure to any Absolute (error between output common mode and voltage at V2). VOS2 includes Maximum Rating condition for extended periods may affect device the combined effects of op amp 2’s voltage offset, IB, IOS and mismatch reliability and lifetime. between on-chip resistors and the 499Ω external resistor, R1 (See Figure 1).
Note 2:
Inputs are protected by diodes to each supply. Additionallly,

Supply voltage range is guaranteed by the power supply rejection op amp inputs +IN1, –IN1 and +IN2 are protected by back-to-back diodes ratio test. across the op amp inputs. If inputs are taken beyond the supplies or if
Note 8:
Output balance is calculated from gain error and gain as: either op amp’s differential input voltage exceeds 0.7V, the input current must be limited to less than 20mA. GAIN BAL =
Note 3:
A heat sink may be required to keep the junction temperature GAINERR below the absolute maximum rating when the output is shorted indefinitely.
