Notes: 1. V_OS = average video output voltage. Measurement excludes first and last pixels.
2. F_S = 2FΦ_T . The minimum clock frequency is limited by the increase in dark signal.

Performance
General measurement conditions: T_C = 25°C; T_i = 1 ms; FΦ_T = 2.5 MHz.
Light source: tungsten filament lamp (2854 K) + BG 38 filter (2 mm thick) + F/3.5 aper-
ture. The filter limits the spectrum to 700 nm; in these conditions, 1 µJ/cm² corresponds
to 3.5 lux.s.
Typical operating conditions; internal clock mode (see Table 2).
First and last pixels, as well as reference elements, are excluded from the specification.
Measurements taken on each output in succession.
