† Unless otherwise noted, all characteristics are measured with both strobes open.

‡ Full range is 0°C to 70°C. MIN is 0°C. MAX is 70°C.

§ This typical value is at VCC+ = 12 V, VCC− = −6 V.

NOTE 5: The offset voltages and offset currents given are the maximum values required to drive the output down to the low range (VOL) or up

to the high range (VOH). These parameters actually define an error band and take into account the worst-case effects of voltage gain

and input impedance.

† All characteristics are measured with both strobes open.

NOTE 6: The response time specified is for a 100-mV input step with 5-mV overdrive and is the interval between the input step function and the

instant when the output crosses 1.4 V.
