output clamping
Output clamping for both upper (V_H) and lower (V_L) levels for the PGAs is provided. There is only one terminal
for the positive output clamp and one for the negative output clamp for both channels.
shutdown control
The SHDN terminals allow for powering down the internal circuitry for power conservation or for multiplexing.
Separate shutdown controls are available for each channel. The control levels are TTL compatible.

† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The THS7001 and THS7002 incorporates a PowerPAD on the underside of the chip. The PowerPAD acts as a heatsink and must
be connected to a thermal dissipation plane for proper power dissipation. Failure to do so can result in exceeding the maximum
junction temperature, which could permanently damage the device. See the Thermal Information section of this document for more
information about PowerPAD technology.
2. For operation above TA = 25°C, derate the THS7001 linearly to 2 W at the rate of 30.6 mW/°C and derate the THS7002 linearly to
2.33 W at the rate of 35.9 mW/°C.
