Product details
Overview
TDA8763M/4/C4,112 from Philips Semiconductors is a 10-bit high-speed low-power analog-to-digital converter (ADC) with internal reference regulator, sampling at up to 40 MHz, delivering 9.3 effective bits at 4.43 MHz full-scale input, and featuring TTL/CMOS-compatible digital outputs with 3–5 V CMOS output stages - used in professional video digitizing and transient signal capture systems.
For engineers reviewing the TDA8763M/4/C4,112 datasheet, TDA8763M/4/C4,112 pinout, TDA8763M/4/C4,112 application, or TDA8763M/4/C4,112 equivalent, this page provides verified technical context, package mapping, real-world timing behavior, SNR and linearity performance at 40 MHz clock, and validated alternatives for video ADC design and high-energy physics instrumentation.
Technical Context
The TDA8763M/4/C4,112 implements a flash-based conversion architecture with one-clock-cycle latency, integrated resistor ladder reference (VRB = 1.3 V, VRT = 3.67 V, Vdiff = 2.3 V), and in-range (IR) CMOS output signaling. It supports DC sampling and accepts low-level AC clock inputs down to 1.5 V peak-to-peak referenced to DGND.
Its analog input path features 5 pF capacitance and 8 kΩ impedance at 4.43 MHz, eliminating need for external buffer or sample-and-hold circuitry. Digital interface uses separate analog (VCCA), dual digital (VCCD1/VCCD2), and output-stage (VCCO) supplies - enabling independent 3.3 V or 5 V output logic levels while maintaining 5 V analog/digital core operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit linear output with no missing codes guaranteed - ensures monotonicity and deterministic code mapping across full input range. |
| Max Sampling Rate | 40 MHz (TDA8763M/4 variant) - enables digitization of baseband video signals up to 15 MHz analog bandwidth with <2 LSB settling error. |
| Effective Bits @ 4.43 MHz | 9.3 bits (typical) - corresponds to ~58 dB SNRFS, sufficient for broadcast-quality PAL/NTSC digitization and radar pulse fidelity. |
| Integral Non-Linearity | ±0.8 LSB (typical) - limits code-dependent gain/offset drift, critical for accurate transient amplitude reconstruction in physics experiments. |
| Power Dissipation | 235 mW (typical at fclk = 40 MHz) - low thermal load enables dense PCB layouts without forced cooling in video acquisition modules. |
| Analog Input Range | 1.95 Vp-p (typical), centered between VRB and VRT - matches standard video signal swing and eliminates need for external level-shifting. |
| Output Compatibility | TTL/CMOS digital inputs; 3–5 V CMOS outputs (VCCO configurable) - interoperable with FPGA I/O banks, ASIC interfaces, and legacy logic families. |
Pinout & Package
SSOP28 package (SOT341-1), plastic shrink small outline, 28 leads, body width 5.3 mm - optimized for high-density video signal processing boards with controlled trace impedance and minimal parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK (1) | Clock input | Accepts low-level sine wave (≥1.5 Vp-p) or square wave; min 0.5 ns rise/fall time required for jitter control. |
| TC (2) | Two's complement mode select | Active LOW; configures D9–D0 output coding format - binary (TC = HIGH) or signed two's complement (TC = LOW). |
| VCCA (3) | Analog supply | +5 V ±5% (4.75–5.25 V); powers analog core and reference regulator - must be decoupled locally with 100 nF + 4.7 nF. |
| AGND (4) | Analog ground | Dedicated return for analog section; isolated from digital grounds to prevent noise coupling into sensitive input path. |
| DEC (5) | Reference decoupling | Connects to AGND via 1 nF capacitor - stabilizes internal reference voltage regulator against supply ripple. |
| VRB (6) | Reference bottom | 1.3 V (typ) - sets lower bound of full-scale input range; internally generated but externally accessible for calibration. |
| VRM (7) | Reference middle | Midpoint (≈2.5 V) of internal resistor ladder - used for offset alignment and differential gain measurement. |
| VI (8) | Analog input | High-impedance (8 kΩ), low-capacitance (5 pF) node - accepts direct connection from video source or RF amplifier output. |
| VRT (9) | Reference top | 3.67 V (typ) - sets upper bound of full-scale range; combined with VRB defines 2.3 V differential reference voltage. |
| OE (10) | Output enable | CMOS-level active LOW; places D9–D0 and IR outputs in high-impedance state - enables bus sharing and multi-ADC synchronization. |
| VCCD2 (11) | Digital supply 2 | +5 V ±5%; powers internal logic and clock driver - shares ground (DGND2) with CLK and TC inputs. |
| DGND2 (12) | Digital ground 2 | Return for VCCD2 and clock domain - kept separate from DGND1 to minimize switching noise injection into data latches. |
| VCCO (13) | Output stage supply | Configurable 3.0–5.25 V; sets VOH/VOL levels for D9–D0 and IR - allows interfacing with 3.3 V FPGAs without level shifters. |
| OGND (14) | Output ground | Dedicated return for VCCO-powered output drivers - prevents digital switching noise from corrupting analog reference stability. |
| n.c. (15) | No connect | Not bonded internally; may be tied to DGND to reduce noise pickup per application note recommendation. |
| D0–D9 (16–25) | Data outputs (LSB to MSB) | CMOS outputs with 1 mA drive strength; VOL ≤ 0.5 V, VOH ≥ VCCO − 0.5 V - compatible with 3.3 V or 5 V logic thresholds. |
| IR (26) | In-range indicator | Active HIGH when VI is within valid conversion range (1.455–3.405 V); flags over/under-range conditions without software polling. |
| DGND1 (27) | Digital ground 1 | Return for VCCD1 and data output logic - routed separately from DGND2 to isolate latch timing paths from clock distribution. |
| VCCD1 (28) | Digital supply 1 | +5 V ±5%; powers data latches and output registers - decoupled independently to maintain timing integrity under heavy bus loading. |

FAQ
What is the maximum clock frequency supported by the TDA8763M/4/C4,112?
The TDA8763M/4/C4,112 supports a maximum clock frequency of 40 MHz, as confirmed in the Quick Reference Data table and Characteristics section of the official Philips datasheet. This rating applies specifically to the M/4 variant and is validated under ramp input conditions at fclk = 40 MHz with typical power dissipation of 235 mW. Exceeding this frequency risks increased DNL/INL errors and potential metastability in the output latches.
Does the TDA8763M/4/C4,112 require an external sample-and-hold circuit?
No, the TDA8763M/4/C4,112 does not require an external sample-and-hold circuit. The datasheet explicitly states "No sample-and-hold circuit required" in the FEATURES section and confirms this in the GENERAL DESCRIPTION. Its flash-converter architecture and low analog input capacitance (5 pF) allow direct sampling of fast-rising signals, with analog input settling time specified at 1.5–3.0 ns for full-scale transitions.
What are the supply voltage requirements for the TDA8763M/4/C4,112 analog and digital sections?
The TDA8763M/4/C4,112 requires three independent supply rails: VCCA (analog supply) and VCCD1/VCCD2 (dual digital supplies) must each be 4.75–5.25 V, while VCCO (output stage supply) operates from 3.0–5.25 V. The datasheet specifies strict supply voltage difference limits: |VCCA − VCCD| ≤ 0.20 V and |VCCA − VCCO| ≤ 2.25 V - necessitating careful decoupling and sequencing in multi-rail designs.
How does the internal reference regulator function in the TDA8763M/4/C4,112?
The TDA8763M/4/C4,112 integrates a reference voltage regulator that generates VRB (1.3 V), VRM (≈2.5 V), and VRT (3.67 V) for its internal resistor ladder. These pins are accessible externally for calibration or daisy-chaining multiple ADCs. The regulator maintains Vdiff = VRT − VRB = 2.3 V (typ), and its temperature coefficient is stabilized via matched resistor ladder design - enabling consistent full-scale range across temperature and unit-to-unit variation.
What is the purpose of the IR (In-Range) output pin on the TDA8763M/4/C4,112?
The IR (In-Range) output pin on the TDA8763M/4/C4,112 is an active-HIGH status flag indicating whether the analog input VI falls within the valid conversion range (1.455 V to 3.405 V). As shown in Table 1, IR = 0 for under-range (U/F) and over-range (O/F) conditions, and IR = 1 for all codes 0–1023. This hardware-level signal eliminates software polling overhead in real-time systems such as Σ∆ modulator feedback control or burst-mode radar acquisition.
