ADC1004S050TS/C1:1
ADC1004S050TS/C1:1 - 10-bit 50MSPS Parallel ADC | NXP | 28-SSOP
The NXP ADC1004S050TS/C1:1 is a 10-bit, 50 MSPS, single-channel, low-power parallel Analog-to-Digital Converter (ADC) housed in a 28-pin SSOP package (SOT-341-1, MO-150). It belongs to the ADC1004S030/040/050 family, and the /C1:1 suffix designates the 50 MSPS speed grade with a commercial 0 °C to +70 °C operating temperature range. The part converts an analog input signal into 10-bit binary-coded digital outputs at a maximum sample rate of 50 MHz and is designed for professional video and high-speed instrumentation applications.
An ADC (Analog-to-Digital Converter) is a mixed-signal integrated circuit that samples a continuous-time analog voltage and produces a discrete-time, finite-resolution digital code. Within the broader signal chain hierarchy, ADCs sit between an analog front end (amplifier, anti-alias filter, MUX) and a digital processor (FPGA, ASIC, microcontroller), and are themselves a member of the data-converter IC family alongside DACs (digital-to-analog converters) and CODECs. The ADC1004S050TS is a flash/half-flash architecture successive-approximation hybrid family, optimized for high sample rate at modest resolution.
Key features of the ADC1004S050TS/C1:1 include a maximum sampling rate of 50 MSPS (the family spans 30/40/50 MHz versions), 10-bit resolution with TTL/CMOS-compatible digital I/O, low-power operation suitable for portable and densely-populated video designs, and an internal reference circuit. The 28-pin SSOP (5.30 mm body width, plastic MO-150 / SOT-341-1) gives a compact surface-mount footprint while preserving good thermal performance for a 28-lead small-outline package.
The device uses a resistance-ladder input stage and a multi-stage comparator architecture, with all digital inputs and outputs TTL and CMOS-compatible. Although a low-level sine-clock input is recommended for lowest jitter, the converter also accepts standard TTL drive levels. The combination of wide analog bandwidth, parallel output bus, and 50 MSPS throughput lets designers sample standard-definition and many enhanced-definition video signals, or perform general-purpose high-speed data acquisition without an external track-and-hold.
Typical applications for the ADC1004S050TS/C1:1 include professional video digitizing and frame grabbers, medical imaging front ends, high-speed instrumentation, CCD/CIS imaging pipelines, and IF/baseband digitizing in communications receivers. The 50 MSPS rate comfortably covers SDTV (27 MHz) and HDTV Y/C (75 MHz on a 10-bit budget, here used with external filtering) sample domains.
When designing with this device, ensure the analog input drive amplifier can settle within the ADC's acquisition window, place the input RC network close to the analog input pin to control charge kick-back, and provide a low-jitter clock with 50 % nominal duty cycle. Decouple VCCA and VCCD independently with 100 nF ceramic capacitors placed as close as possible to the supply pins.
