Philips Semiconductors
8-bit, low-power, 3 V, 100 Msps
Analog-to-Digital Converter (ADC)
Preliminary specification
TDA8793
CHARACTERISTICS
V_CCA = V₇ to V₆ = 2.7 to 3.6 V; V_CCD = V₁₀ to V₉ = 2.7 to 3.6 V; V_CCO = V₂₀ (or V₂₂) to V₁₉ (or V₂₁) = 2.7 to 3.6 V;
AGND to DGND and OGND shorted together; V_CCA to V_CCD = −0.15 to +0.15 V; V_CCD to V_CCO = −0.15 to +0.15 V;
V_CCA to V_CCO = −0.15 to +0.15 V; T_amb = 0 to 70 °C; typical values measured at V_CCA = V_CCD = V_CCO = 3.0 V and
T_amb = 25 °C; single-ended input; unless otherwise specified.
