Product details
Overview
ADC1003S040TS/C1:1 from NXP Semiconductors is a 10-bit, 40 MHz sampling rate analog-to-digital converter with internal voltage reference regulator, TTL/CMOS-compatible digital I/O, and in-range (IR) CMOS output. It operates with separate 5 V analog/digital supplies and 3–5 V output supply, supports DC sampling, and delivers 9.3 effective bits at 4.43 MHz full-scale input - optimized for professional video digitizing and radar signal acquisition.
For engineers reviewing the ADC1003S040TS/C1:1 datasheet, ADC1003S040TS/C1:1 pinout, ADC1003S040TS/C1:1 application, or ADC1003S040TS/C1:1 equivalent, this page provides verified specifications including clock timing (8.5 ns HIGH pulse width), INL (±0.8 LSB), power dissipation (235 mW typ), analog input bandwidth (15 MHz), and SSOP28 package mapping - all confirmed from NXP's Rev. 02 product data sheet dated 7 August 2008.
Technical Context
The ADC1003S040TS/C1:1 implements a resistor ladder architecture with external reference pins (RB, RM, RT) and internal voltage regulator, enabling precise differential reference voltage (2.3 V typ) and low offset error (±1 LSB). Its one-clock-cycle conversion latency and IR output latch support real-time video and transient capture without external sample-and-hold circuitry.
It features dual-ground separation (AGND/DGND/OGND), three independent supply domains (VCCA, VCCD, VCCO), and AC-coupled clock input compatibility - allowing integration into mixed-signal systems requiring strict noise isolation and flexible logic-level interfacing across 3.3 V or 5 V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit linear output with no missing codes guaranteed - ensures monotonicity for precision measurement and video reconstruction. |
| Max Sampling Rate | 40 MHz - enables digitization of baseband video signals (e.g., PAL/NTSC) and intermediate-frequency radar returns. |
| Effective Bits (ENOB) | 9.3 bits at fclk = 40 MHz, fin = 4.43 MHz - translates to ~58 dB SNR, suitable for broadcast-grade video digitizing. |
| Integral Non-Linearity | ±0.8 LSB (typ) - minimizes harmonic distortion in high-fidelity signal acquisition paths. |
| Total Power Dissipation | 235 mW (typ) at 40 MHz ramp input - supports thermal management in dense PCB layouts without forced cooling. |
| Analog Input Bandwidth | 15 MHz (full-scale sine wave) - captures harmonics up to third order for composite video and GPS IF signals. |
| Clock Pulse Width (HIGH) | 8.5 ns minimum - defines minimum duty cycle constraint for stable sampling at 40 MHz operation. |
Pinout & Package
ADC1003S040TS/C1:1 is housed in a plastic shrink small outline package (SSOP28), SOT341-1 variant, with 28 leads and 5.3 mm body width. Pin pitch is 0.65 mm; thermal resistance Rth(j-a) is 110 K/W in free air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK (1) | Clock input | Accepts low-level AC sine wave or TTL/CMOS square wave; rise/fall time ≥ 0.5 ns required. |
| TC (2) | Two's complement mode select | Active LOW; configures D9–D0 output coding between binary (TC = 1) and two's complement (TC = 0). |
| VCCA (3) | Analog supply | +4.75 V to +5.25 V; powers analog core and reference ladder; must be decoupled near pin. |
| AGND (4) | Analog ground | Reference for VI, RB, RM, RT; must be shorted to DGND externally per layout guidelines. |
| D0–D9 (16–25) | Data outputs | CMOS-level, 3–5 V tolerant; output valid after td(o) ≤ 13 ns (VCCO = 4.75 V); 3-state controlled by OE. |
| IR (26) | In-range flag | Active HIGH when VI is within valid code range (0–1023); used for overflow/underflow detection in real-time systems. |
| OE (10) | Output enable | Active LOW; places D9–D0 and IR in high-impedance state - enables bus sharing in multi-ADC architectures. |
| RB / RM / RT (6/7/9) | Reference ladder taps | Set differential reference (VRT − VRB = 2.3 V typ); allow external trimming or replacement of internal regulator. |
Key Features
| Feature | Design Value |
|---|---|
| No sample-and-hold required | Enables direct connection of video or RF IF signals without external buffering - reduces BOM count and board area. |
| Low analog input capacitance (5 pF) | Minimizes loading on upstream amplifiers or filters; eliminates need for driver stage in many video front-ends. |
| One-clock-cycle conversion | Guarantees deterministic latency (td(s) = 3 ns) - critical for time-sensitive applications like radar pulse analysis. |
| Separate output supply (VCCO = 3–5 V) | Allows seamless interface to 3.3 V FPGA or ASIC logic without level shifters - simplifies system voltage domain partitioning. |
| Internal voltage reference regulator | Provides stable 2.3 V differential reference; optional external drive via RB/RT supports higher accuracy or multi-device matching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog-to-digital conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC1004S040 | Pin-to-pin compatible; replaces internal reference with external reference input only - requires external reference IC or resistor network. | Better suited for systems needing matched references across multiple ADCs or tighter temperature drift control. | Select ADC1004S040 when reference accuracy or inter-device matching outweighs convenience of internal regulator. |
| ADC1005S060 | 60 MHz max sampling rate; same SSOP28 package but higher power (340 mW typ); no internal reference - reference must be fully external. | Required for digitizing >40 MHz IF bands (e.g., LTE, Wi-Fi) where 40 MHz limit of ADC1003S040TS/C1:1 is insufficient. | Choose ADC1005S060 only when system clock exceeds 40 MHz and external reference infrastructure already exists. |
Compared with ADC1004S040 and ADC1005S060, ADC1003S040TS/C1:1 uniquely balances integrated reference convenience, 40 MHz performance, and 235 mW power - making it optimal for cost-sensitive, space-constrained video and radar designs where external reference complexity must be avoided.

FAQ
What is the maximum clock frequency supported by ADC1003S040TS/C1:1?
The ADC1003S040TS/C1:1 supports a maximum clock frequency of 40 MHz, as specified in Table 1 and Table 6 of the NXP product data sheet Rev. 02. This rating is validated under standard conditions (VCCA = VCCD = 5 V, VCCO = 3.3 V, Tamb = 25 °C) and defines the upper limit for reliable sampling without timing violations or code errors in ADC1003S040TS/C1:1 operation.
Does ADC1003S040TS/C1:1 require an external sample-and-hold circuit?
No, ADC1003S040TS/C1:1 does not require an external sample-and-hold circuit. Its architecture supports direct sampling of analog inputs with 1.5–3.0 ns settling time, as confirmed by ts(LH)/ts(HL) specifications in Table 6. This eliminates added latency and component count in ADC1003S040TS/C1:1-based video and radar signal chains.
What are the supply voltage requirements for ADC1003S040TS/C1:1?
ADC1003S040TS/C1:1 requires three independent supplies: VCCA and VCCD at 4.75–5.25 V (analog and digital cores), and VCCO at 3.0–5.25 V (output drivers). Per Table 6, ∆VCC tolerances are tight (e.g., VCCA − VCCD ≤ ±0.20 V), and all grounds (AGND, DGND, OGND) must be shorted externally per NXP layout guidance for ADC1003S040TS/C1:1.
How does the IR (In-Range) output function in ADC1003S040TS/C1:1?
The IR pin (Pin 26) of ADC1003S040TS/C1:1 outputs HIGH when the analog input VI falls within the valid 10-bit code range (0–1023), and LOW for underflow (<1.455 V) or overflow (>3.405 V). As shown in Table 7, IR enables real-time signal integrity monitoring without host processor intervention - a key feature for autonomous ADC1003S040TS/C1:1 systems in video and radar.
Is ADC1003S040TS/C1:1 pin-compatible with ADC1004S040?
Yes, ADC1003S040TS/C1:1 is pin-compatible with ADC1004S040, as confirmed in Table 9 ("Alternative parts") of the NXP datasheet, which explicitly states "[1] Pin to pin compatible". Both use identical SSOP28 (SOT341-1) packaging and share identical pin functions - though ADC1004S040 omits the internal reference regulator and requires external reference drive.
