Analog inputs, VI

Error amp output sink current, ISINK(EA)

Power dissipation (TA = 25 OC), PD

Maximum junction temperature TJ

Storage temperature range

Lead temperature (soldiering, 10 seconds)

35V

± 1A

-0.3V to 6.3V

10mA

1W

150OC

-65OC to 150OC

Note 5: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground.

Currents are positive into, negative out of the specified terminal.

THERMAL DATA

PDIP PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

SOIC PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

Junction Temperature Calculation: TJ = TA + (PD × θJA).

The θJA numbers are guidelines for the thermal performance of the device/pc-board system.

All of the above assume no ambient airflow.

95 OC/W

165 OC/W
