Technical content

General description The ADC0801S040 is an 8-bit universal analog-to-digital converter (ADC) for video and general purpose applications. It converts the analog input signal from 2.7 V to 5.5 V into 8-bit binary-coded digital words at a maximum sampling rate of 40 MHz. All digital inputs and outputs are CMOS/Transistor-Transistor Logic (TTL) compatible. A sleep mode allows reduction of the device power consumption to 4 mW. 2. Features n 8-bit resolution n Operation between 2.7 V and 5.5 V n Sampling rate up to 40 MHz n DC sampling allowed n High signal-to-noise ratio over a large analog input frequency range (7.3 effective bits at 4.43 MHz full-scale input at fclk = 40 MHz) n CMOS/TTL compatible digital inputs and outputs n External reference voltage regulator n Power dissipation only 30 mW (typical value) n Low analog input capacitance, no buffer ampliﬁer required n Sleep mode (4 mW) n No sample-and-hold circuit required 3. Applications n Video data digitizing n Camera n Camcorder n Radio communication n Car alarm system ADC0801S040 Single 8 bits ADC, up to 40 MHz Rev. 02 — 18 August 2008 Product data sheet

12.1 Application diagrams

The analog and digital supplies should be separated and decoupled. The external voltage reference generator must be built in such a way that a good supply voltage ripple rejection is achieved with respect to the LSB value. Eventually, the reference ladder voltages can be derived from a well regulated V DDA supply through a resistor bridge and a decoupling capacitor. (1) RB, RM, RT are decoupled to VSSA . Fig 15.
