THS4131: Device getting hot

Part Number: THS4131

Hi Team,

Can you help diagnose the customer issue below?

A customer is testing the device using the schematic from the datasheet (see below). 

In this test, the customer grounded both inputs instead of having a source voltage (a 10V DC source was connected in a different test which resulted in a package temperature of 113C), A 10k value is used for all the resistors, and Vocm pin was connected via a  0.1uF capacitor to ground. the value of Vcc+ was +15V and Vcc- was -15V. The result of this test was a package temperature of 85C which seemed high considering the device is in an idle state.

Could confirm whether this behavior is as expected?

Thank you.
