1 Thermoelectric voltages present in the high speed production test limit the measurement accuracy of this parameter. The limits shown in Table 1 are determined by test

capability and are not necessarily indicative of actual device performance.

2 Offset voltage drift is guaranteed through lab characterization and is not production tested.

3 Test accuracy is limited by high speed production test equipment repeatability. Bench measurements indicate that the input offset current in Over-The-Top configuration is

typically controlled to under 50 nA at +25°C and 100 nA over the −55°C < TA < +150°C temperature range.

4 VOD is +30 mV for VOUT high and −30 mV for VOUT low.

5 Maximum operating voltage is limited by the time-dependent dielectric breakdown (TDDB) of the on-chip capacitor oxides. The amplifiers tolerate temporary transient

overshoot up to the specified absolute maximum rating, but the dc supply voltage must be limited to the maximum operating voltage.

6 Thermal shutdown is lab characterized only and is not tested in production.

VCM = 0 V, SHDN pin (ADA4098-1) and SHDNx pins (ADA4098-2 10-lead LFCSP) are open, RL = 499 kΩ to ground, and TA = 25°C, unless

otherwise noted.
