ADC1004S030/040/050
Single 10 bits ADC, up to 30 MHz, 40 MHz or 50 MHz
Rev. 04 — 2 July 2012
Product data sheet
1. General description
The ADC1004S030/040/050 are a family of 10-bit high-speed low-power Analog-to-Digital
Converters (ADC) for professional video and other applications. They convert the analog
input signal into 10-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 is allowed.
The device requires an external source to drive its reference ladder. If the application
requires that the reference is driven via internal sources, Integrated Device Technology
recommends you use one of the ADC1003S030/040/050 family.

In addition to a good layout of the digital and analog ground, it is recommended that the rise and fall times of the clock must not be less
than 0.5 ns.
[2]
Analog input voltages producing code 0 up to and including code 1023:
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 1023 at Tamb = 25 C.
[3]
In order to ensure the optimum linearity performance of such converter architecture the lower and upper extremities of the converter
reference resistor ladder (corresponding to output codes 0 and 1023 respectively) 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 1023 is V I = R L  I L = ---------------------------------------   V RT + V RB  = 0.852   V RT – V RB 
R OB + R L + R OT
RL
--------------------------------------b) Since RL, ROB and ROT have similar behavior with respect to process and temperature variation, the ratio R OB + R L + R OT
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.

The analog bandwidth is defined as the maximum input sine wave frequency which can be applied to the device. No glitches greater
than 2 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.

ADC1004S030/040/050
Integrated Device Technology
Single 10 bits ADC, up to 30 MHz, 40 MHz or 50 MHz
[7]
Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8000 acquisition points per equivalent fundamental
period. The calculation takes into account all harmonics and noise up to half of the clock frequency (Nyquist frequency). Conversion to
signal-to-noise 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(max). For 50 MHz version Integrated Device
Technology recommends the lowest possible output load.

The analog and digital supplies should be separated and well decoupled
A user manual is available that describes the demonstration board that uses the version ADC1004S030/040/050 family with an
application environment.
(1) RB, RM and RT are decoupled to AGND.
(2) Pin 15 may be connected to DGND in order to prevent noise influence.
(3) Decoupling capacitor for supplies; must be placed close to the device.
