6-bit analog-to-digital converter with
multiplexer and clamp
TDA8706
Notes to the characteristics
1.
Low frequency ramp signal (V
VI(p-p)
= 1.8 V and f
i
= 15 kHz) combined with a sinewave input voltage (V
VI(p-p)
= 0.5 V
and f
i
= 4.43 MHz) at the input.
2.
Supply voltage ripple rejection (SVRR): variation of the input voltage produces output code 31 for a supply voltage
variation of 1 V.
