Product details
Overview
ADC0804S030TS/C1:1 from NXP Semiconductors is an 8-bit, 30 MHz sampling-rate analog-to-digital converter optimized for professional video digitization and high-speed transient signal capture. It features TTL/CMOS-compatible digital I/O, external reference ladder architecture, one-cycle conversion latency, and 7.8 effective bits at 4.43 MHz full-scale input - deployed in GPS receivers and medical imaging front-ends.
For engineers reviewing the ADC0804S030TS/C1:1 datasheet, ADC0804S030TS/C1:1 pinout, ADC0804S030TS/C1:1 application, or ADC0804S030TS/C1:1 equivalent, key selection criteria include its SSOP28 package, 30 MHz clock limit, dual-supply operation (5 V analog/digital, 3–5 V output), INL ±0.5 LSB, and absence of internal reference regulator - requiring external precision resistor ladder biasing.
Technical Context
This ADC employs a flash-converter architecture with integrated in-range (IR) CMOS latch and three-state digital outputs controlled by OE and TC pins. Conversion is synchronized to a single-edge clock input, with no sample-and-hold circuit required due to low analog input capacitance (5 pF) and DC sampling capability.
It uses an external resistor ladder referenced via RB, RM, and RT pins to define the 2.37 V differential reference voltage (VRT − VRB), enabling precise gain/offset control. The analog input operates over 1.475 V to 3.495 V (typical), with binary or two's complement output coding selected by TC pin state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit linear output with guaranteed no missing codes |
| Max Sampling Rate | 30 MHz - defines maximum real-time signal bandwidth without aliasing |
| Effective Bits | 7.8 bits at 4.43 MHz input - quantifies usable dynamic range under video-band conditions |
| INL / DNL | ±0.5 LSB / ±0.22 LSB - ensures monotonicity and accurate code transition thresholds |
| Power Dissipation | 175 mW typical at 40 MHz - enables thermal management in dense video processing modules |
| Analog Input Range | 1.7–2.55 Vp-p - sets required signal conditioning gain before digitization |
| Reference Architecture | External ladder (RB/RM/RT pins) - mandates external precision resistors but avoids internal reference drift |
Pinout & Package

| TC (2) | Two's complement select | Active-LOW control for signed output coding (vs. binary when HIGH) |
| VCCA (3) | Analog supply | +4.75 V to +5.25 V analog rail; must be decoupled near AGND |

Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum clock frequency supported by ADC0804S030TS/C1:1?
The ADC0804S030TS/C1:1 supports a maximum clock frequency of 30 MHz, as specified in Table 1 and confirmed in Table 6 of the NXP datasheet. This defines the upper limit for sampling rate and directly constrains analog input bandwidth to ≤15 MHz for Nyquist-compliant operation. Exceeding this frequency risks metastability and invalid output codes.
Does ADC0804S030TS/C1:1 include an internal voltage reference?
No, ADC0804S030TS/C1:1 does not include an internal voltage reference. It requires an external resistor ladder connected to pins RB, RM, and RT to establish the reference voltage - a design choice that enables system-level calibration and temperature compensation. NXP explicitly recommends the ADC1003S series for applications needing internal reference regulation.
What are the supply voltage requirements for ADC0804S030TS/C1:1?
ADC0804S030TS/C1:1 requires three independent supply rails: VCCA and VCCD at 4.75–5.25 V (analog and digital cores), and VCCO at 3.0–5.25 V (output driver stage). The datasheet specifies strict voltage difference limits (e.g., |VCCA − VCCD| ≤ 0.20 V) to prevent latch-up and ensure reliable operation across temperature.
How is output coding selected on ADC0804S030TS/C1:1?
Output coding on ADC0804S030TS/C1:1 is selected via the TC (two's complement) pin: when TC is LOW, outputs follow two's complement format; when TC is HIGH, outputs are in straight binary format. This selection is latched on the rising edge of CLK and applies to all eight data bits (D7–D0) and the IR flag.
What does the IR (In-Range) output indicate on ADC0804S030TS/C1:1?
The IR output on ADC0804S030TS/C1:1 is an active-HIGH signal that indicates the analog input voltage VI falls within the valid conversion range (code 0 to 255). It goes LOW for underflow (<1.475 V) or overflow (>3.495 V), providing real-time validity feedback without requiring host-side range checking - critical for high-speed streaming applications.
