TDA8706AM/C3,118

ADCs/DACs - Special Purpose Overview

The TDA8706A is a 6-bit analog-to-digital converter (ADC) featuring an integrated analog multiplexer and clamping circuitry. It supports three multiplexed video inputs (RED, GREEN, BLUE) with individual clamps on code 0, adjustable externally up to code 20. The device operates on single supplies between 2.7 V and 3.6 V for analog, digital, and output stages. It achieves a maximum clock frequency of 40 MHz with typical power dissipation of 36 mW. Integral non-linearity is ±0.5 LSB and differential non-linearity is ±0.35 LSB at full speed. The component is housed in a 24-lead SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the current product status as the datasheet indicates supersession of earlier versions from 1996. Confirm supply availability through authorized NXP or Philips Semiconductors distributors, as older components may be subject to end-of-life restrictions. Ensure ordering suffixes match the required package variant.

ADCs/DACs - Special Purpose Selection Notes

Select this component for low-power video digitization requiring multiplexed RGB inputs. Ensure the system clock does not exceed 40 MHz. Verify that the input voltage amplitude stays within the 0.63 V to 0.77 V peak-to-peak range. Check that the operating temperature range of -40 °C to +85 °C meets environmental requirements.

ADCs/DACs - Special Purpose Part Context

This part is a 6-bit ADC from the Philips/NXP semiconductor portfolio, originally specified under Philips Semiconductors branding. It serves as a specialized converter for video signals, distinct from general-purpose high-resolution ADCs. The device integrates analog front-end functions like clamping to simplify PCB design for video processing applications.

ADCs/DACs - Special Purpose Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Designers should evaluate other 6-bit video ADCs with similar pinouts and specifications if this component is unavailable.
