sampling mode. It is greater than tracking bandwidth because it does not include the bandwidth of the output amplifier.

noise is typically 3

µV (150 mV/s x 20 ns). This value must be combined with the track mode noise to obtain total noise.

Typical thermal impedances:

ΘJC (LCC) = +6 °C/W

ΘJA (SOIC) = +85 °C/W in still air at +25 °C ambient.

≤0.8 volts to maintain device in linear range.
