ADC0804S030/040/050 Single 8 bits ADC, up to 30 MHz, 40 MHz or 50 MHz Rev. 03 — 2 July 2012 Product data sheet 1. General description The ADC0806030/040/050 are a family of 8-bit high-speed, low-power Analog-to-Digital Converters (ADC) for professional video and other applications. It converts the analog input signal into 8-bit binary coded digital signals at a maximum sampling rate of 50 MHz. All digital inputs and outputs are Transistor-Transistor Logic (TTL) and CMOS compatible, although a low-level sine wave clock input signal can also be used. The device requires an external source to drive its reference ladder. If the application requires that the reference is driven via internal sources, IDT recommends you use one of the ADC1003S030/040/050 family. 2. Features 8-bit resolution Sampling rate up to 50 MHz DC sampling allowed One clock cycle conversion only High signal-to-noise ratio over a large analog input frequency range (7.8 effective bits at 4.43 MHz full-scale input at fclk = 40 MHz) No missing codes guaranteed In-Range (IR) CMOS output TTL and CMOS levels compatible digital inputs 3 V to 5 V CMOS digital outputs Low-level AC clock input signal allowed External reference voltage regulator Power dissipation only 175 mW (typical) Low analog input capacitance, no buffer amplifier required No sample-and-hold circuit required 3.

[2] Analog input voltages producing code 0 up to and including code 255: a) Voffset BOTTOM is the difference between the analog input which produces data equal to 00 and the reference voltage on pin RB (VRB) at Tamb = 25 C. b) Voffset TOP is the difference between the reference voltage on pin RT (VRT) and the analog input which produces data outputs equal to code 255 at Tamb = 25 C. [3] To ensure the optimum linearity performance of such a converter architecture the lower and upper extremities of the converter reference resistor ladder are connected to pins RB and RT via offset resistors ROB and ROT as shown in Figure 3. V RT – V RB R OB + R L + R OT a) The current flowing into the resistor ladder is I = --------------------------------------- and the full-scale input range at the converter, to cover code 0 RL to 255 is V I = R L I L = --------------------------------------- V RT + V RB = 0.852 V RT – V RB R OB + R L + R OT RL R OB + R L + R OT b) Since RL, ROB and ROT have similar behavior with respect to process and temperature variation, the ratio --------------------------------------will be kept reasonably constant from device to device. Consequently, the variation of the output codes at a given input voltage depends mainly on the difference VRT VRB and its variation with temperature and supply voltage. When several ADCs are connected in parallel and fed with the same reference source, the matching between each of them is optimized. [4] V 1023 – V 0 – V i p – p E G = ------------------------------------------------------- 100 Vi p – p [5] The analog bandwidth is defined as the maximum input sine wave frequency which can be applied to the device. No glitches greater than 0.5 LSB, neither any significant attenuation are observed in the reconstructed signal. [6] The analog input settling time is the minimum time required for the input signal to be stabilized after a sharp full-scale input (square wave signal) in order to sample the signal and obtain correct output data.

The calculation takes into account all harmonics and noise up to half the clock frequency (Nyquist frequency). Conversion to SIgnal-to-Noise-And-Distortion (SINAD) ratio: SINAD = ENOB 6.02 + 1.76 dB. [8] Intermodulation measured relative to either tone with analog input frequencies of 4.43 MHz and 4.53 MHz. The two input signals have the same amplitude and the total amplitude of both signals provides full-scale to the converter. [9] Measurement carried out using video analyzer VM700A, where the video analog signal is reconstructed through a digital-to-analog converter. [10] Output data acquisition: the output data is available after the maximum delay time of td(0). For 50 MHz version IDT recommend the lowest possible output load.
