Texas Instruments TLC876IPWLE

Overview

TLC876IPWLE from Texas Instruments is a 10-bit, 20 MSPS parallel-output CMOS analog-to-digital converter (ADC) designed for high-speed video and imaging signal acquisition. It features differential nonlinearity of ±0.5 LSB typ, 5-V single-supply operation, and power dissipation of 107 mW typ at full speed - enabling use in CCD-based digital copiers, electronic still cameras, and TMS320C6x DSP front-ends.

For engineers reviewing the TLC876IPWLE datasheet, TLC876IPWLE pinout, TLC876IPWLE application, or TLC876IPWLE equivalent, key selection considerations include its pipelined multistage architecture with 3.5-clock-cycle latency, force-sense reference interface for precision span control, 3-state digital outputs compatible with 3.3-V/5-V logic, and –40°C to 85°C industrial temperature rating.

Technical Context

The TLC876IPWLE implements a 5-stage pipelined ADC architecture with output error correction logic, enabling no missing codes across its full operating temperature range. Each stage includes a sample-and-hold amplifier (SHA), allowing concurrent processing of five successive samples per clock cycle.

It uses force-sense reference terminals (REFTF/REFTS and REFBF/REFBS) to compensate for internal 5-Ω wiring resistance, ensuring accurate 2-Vpp input span determination. The analog input supports ac-coupled or dc-coupled configurations, with aperture jitter specified at 22 ps and full-power analog bandwidth of 200 MHz.

FAQ

What is the operating temperature range for the TLC876IPWLE?

The TLC876IPWLE is rated for industrial operation from –40°C to +85°C, matching the TLC876I grade. This range ensures reliable performance in digital camcorders, scanners, and embedded vision systems exposed to ambient thermal variation without requiring active cooling or derating.

Does the TLC876IPWLE support 3.3-V digital logic interfaces?

Yes, the TLC876IPWLE supports 3.3-V digital I/O via the DRVDD pin, which accepts 3 V to 5.25 V. When DRVDD = 3.3 V, VOH is ≥2.4 V and VOL is ≤0.7 V under 50-µA load - meeting standard 3.3-V LVTTL/LVCMOS interface requirements without level shifters.

How does the force-sense reference interface improve accuracy in the TLC876IPWLE?

The TLC876IPWLE uses REFTF/REFTS and REFBF/REFBS pairs to eliminate voltage drop errors across internal 5-Ω paths. By routing reference current through force terminals and sensing voltage at sense terminals, the device achieves precise 2-Vpp span definition - critical for maintaining 10-bit linearity in production systems with variable PCB trace resistance.

What is the pipeline latency of the TLC876IPWLE, and how does it affect system timing?

The TLC876IPWLE has a fixed pipeline latency of 3.5 clock cycles. This means the first valid output corresponding to an input sample appears 3.5 CLK periods after sampling begins. System designers must account for this deterministic delay when synchronizing with downstream DSPs or FIFOs - especially in real-time video pipelines where frame alignment is critical.

Can the TLC876IPWLE operate with a single 5-V supply, and what are the supply partitioning requirements?

Yes, the TLC876IPWLE operates from a single 5-V source, but supplies must be partitioned: AVDD and DVDD each require dedicated 5-V rails decoupled separately, with voltage difference ≤0.5 V between them. DRVDD may be 3.3 V or 5 V. Mixing analog/digital grounds (AGND/DGND/DRGND) on a common plane degrades SNR and must be avoided.
