Typical Application

Figure 1. Strain Gauge Bridge Amplifier

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

Absolute Maximum Ratings indicate limits beyond which damage may occur. Operating Ratings indicate conditions for which the device

is intended to be functional, but specific performance is not ensured. For ensured specifications and test conditions, see the Electrical

Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of

JEDEC)Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).

(4)

The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is

PD = (TJ(MAX) – TA)/ θJA. All numbers apply for packages soldered directly onto a PC Board.
