Notes
1. At Tj = 125 °C, the temperature coefficient of the Vloss has a positive sign.
2. The linearity error is measured for a linear input signal without S correction and is based on the ‘on screen’
measurement principle. This method is defined as follows. The output signal is divided into 22 successive equal time
parts. The 1st and 22nd parts are ignored. The remaining 20 parts form 10 successive blocks k, where a block
consists of two successive parts. The voltage amplitudes are measured across RM, starting at k = 1 and ending at
k = 10, where Vk and Vk + 1 are the measured voltages of two successive blocks. Vmin, Vmax and Vav are the
minimum, maximum and average voltages respectively. The linearity errors are defined as:
LE = V-----k----–V----V-a--v-k----+----1- × 100% (adjacent blocks) and LE = -V----m----a--xV----–a---v-V-----m---i-n- × 100% (non-adjacent blocks).
3. Vo(A) + Vo(B) = VP. At the start of the scan, this equation is one diode voltage less.
4. The V value within formulae relates to voltages at or between relative pin numbers, i.e. V9 to 5/V3 to 5 = voltage value
across pins 9 and 5, divided by voltage value across pins 3 and 5.
5. V2 to 5 AC short circuited.
6. At Vripple = 500 mVeff at VP; measured across RM; fripple = 50 Hz to 1 kHz.
7. Ii(abs)(max) = 800 µA and Ii(abs)(min) = 50 µA per pin.
