NXP Semiconductors TDA8763AM/4/C4,118

Overview

TDA8763AM/4/C4,118 from Philips Semiconductors is a 10-bit high-speed low-power analog-to-digital converter (ADC) designed for professional video digitization and transient signal capture. It delivers up to 40 MHz sampling rate, 9.4 effective bits at 4.43 MHz input with 40 MHz clock, and 175 mW typical power dissipation. Its CMOS-compatible In-Range (IR) outputs and external reference ladder support precision video data acquisition in broadcast and instrumentation systems.

For engineers reviewing the TDA8763AM/4/C4,118 datasheet, TDA8763AM/4/C4,118 pinout, TDA8763AM/4/C4,118 application, or TDA8763AM/4/C4,118 equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in the official 1999 Philips product specification.

Technical Context

The TDA8763AM/4/C4,118 implements a flash-based ADC architecture with a resistor ladder reference network (VRB/VRM/VRT pins), enabling single-clock-cycle conversion and DC sampling capability. Its analog input accepts ±10 LSB at mid-scale with 5 pF input capacitance and no buffer or sample-and-hold circuit required.

It features dual digital supply domains (VCCD1/VCCD2), independent output-stage supply (VCCO = 3–5 V), and TTL/CMOS-compatible I/O with low-level AC clock support. The IR output indicates valid code range, while TC pin selects two's complement or binary coding - both confirmed in Table 2 of the datasheet.

FAQ

What is the maximum clock frequency supported by the TDA8763AM/4/C4,118?

The TDA8763AM/4/C4,118 supports a maximum clock frequency of 40 MHz, as explicitly specified in the Quick Reference Data table and confirmed in the Switching Characteristics section. This rating applies under standard operating conditions (T_amb = 0 to +70 °C, V_CCA/V_CCD = 4.75–5.25 V). Exceeding 40 MHz may result in degraded INL/DNL or missing codes, and the device is not characterized beyond this limit.

Does the TDA8763AM/4/C4,118 require an external sample-and-hold circuit?

No, the TDA8763AM/4/C4,118 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 in the GENERAL DESCRIPTION that the device performs direct sampling. Its 1.5 ns analog input settling time and 5 pF input capacitance allow direct connection to well-driven sources such as video amplifiers or RF mixers.

What is the function of the IR pin on the TDA8763AM/4/C4,118?

The IR (In-Range) pin on the TDA8763AM/4/C4,118 is an active-HIGH CMOS output that indicates whether the current digital output code falls within the valid 0–1023 range. As shown in Table 1, IR = 0 for underflow (VI < 1.475 V) and overflow (VI > 3.495 V), and IR = 1 for all codes 0–1023. This enables hardware-level overflow/underflow detection without reading D9–D0 data.

Can the TDA8763AM/4/C4,118 operate with a 3.3 V digital supply?

Yes, the TDA8763AM/4/C4,118 supports 3.3 V for its output-stage supply (V_CCO), which ranges from 3.0 to 5.25 V per the CHARACTERISTICS table. However, its analog (V_CCA) and core digital (V_CCD1/V_CCD2) supplies require 4.75–5.25 V and are not rated for 3.3 V operation. Using 3.3 V on V_CCA or V_CCD violates Absolute Maximum Ratings and risks functional failure.

What reference voltage configuration is required for the TDA8763AM/4/C4,118?

The TDA8763AM/4/C4,118 requires three external reference voltages applied to VRB (bottom), VRM (middle), and VRT (top) pins. Typical values are VRB = 1.3 V and VRT = 3.67 V, yielding a 2.37 V differential reference. These must be decoupled individually to AGND per Fig.14. The device contains no internal reference; all reference generation and regulation must be provided externally.
