ISL28190, ISL28290
Electrical Specifications
V₊= 5.0V, V_-= GND, R_L = 1kΩ, R_F = 1kΩ, A_V = -1. unless otherwise specified. Parameters are per amplifier.
Typical values are at V+= 5V, T_A = +25°C. Boldface limits apply over the operating temperature range,
-40°C to +125°C, temperature data guaranteed by characterization
