Texas Instruments TLC5510IPWR

Overview

TLC5510IPWR from Texas Instruments is a CMOS 8-bit, 20 MSPS analog-to-digital converter (ADC) using a semiflash architecture for high-speed video and communication signal digitization. It features 2-V full-scale input range, ±0.75 LSB integral nonlinearity at 25°C, 5-V single-supply operation, and parallel high-impedance digital outputs - deployed in digital TV front-ends and QAM demodulator signal chains.

For engineers reviewing the TLC5510IPWR datasheet, TLC5510IPWR pinout, TLC5510IPWR application, or TLC5510IPWR equivalent, this page delivers verified technical context, package-specific terminal mapping, real-world application constraints, and validated alternative options - all grounded in TI's SLAS095L production data sheet and packaging addendum.

Technical Context

The TLC5510IPWR implements a 2-step semiflash conversion architecture with upper and lower 4-bit comparator blocks, reducing comparator count versus full-flash designs while maintaining 20 MSPS throughput. Its internal resistor divider (320 Ω / 270 Ω / 80 Ω) generates a nominal 2-V reference when REFTS–REFT and REFBS–REFB are shorted, eliminating external reference components for standard video-level inputs.

Latency is fixed at 2.5 clock cycles from analog sampling to valid D1–D8 output. The device integrates an on-chip sample-and-hold, dual ground domains (AGND/DGND), and OE-controlled high-impedance output mode - enabling synchronous data capture in burst-mode or multiplexed bus systems without external latches.

FAQ

What is the full-scale input voltage range of the TLC5510IPWR?

The TLC5510IPWR has a 2-V full-scale analog input range, defined as the voltage span from VREFB to VREFT (typically 0.5 V to 2.5 V). This is implemented using TI's internal 3-resistor divider network between VDDA and AGND - requiring only jumper shorts between REFT/REFTS and REFB/REFBS. External reference sources are not needed for standard operation.

Does the TLC5510IPWR support high-impedance digital outputs?

Yes, the TLC5510IPWR supports high-impedance digital outputs via its active-low OE (output enable) pin. When OE is driven high, all eight data pins (D1–D8) enter a high-impedance state, allowing multiple TLC5510IPWR devices to share a common data bus without contention. This feature eliminates the need for external tri-state buffers in multi-channel acquisition systems.

What package type and dimensions does the TLC5510IPWR use?

The TLC5510IPWR uses a 24-pin TSSOP (PW) package measuring 7.7 mm × 4.4 mm with 0.65 mm lead pitch and 1.2 mm maximum height. It is supplied in tape-and-reel format (2000 units per reel) and complies with JEDEC MO-153 standards. The package includes exposed thermal pad geometry optimized for reflow soldering and thermal dissipation in high-density layouts.

How does the TLC5510IPWR achieve 20 MSPS conversion rate with low power?

The TLC5510IPWR achieves 20 MSPS at 127.5 mW typical power by using a semiflash architecture - splitting conversion into two 4-bit stages instead of a full 8-bit flash array. This reduces comparator count by >75%, cutting die area and static/dynamic power. The internal sample-and-hold and optimized clock distribution further minimize switching losses while maintaining 2.5-clock latency.

Is the TLC5510IPWR pin-compatible with the TLC5510A variants?

No, the TLC5510IPWR is not pin-compatible with TLC5510A variants such as TLC5510AINSR. While both share identical 24-pin TSSOP/SOP footprints and pin numbering, their reference configurations differ fundamentally: TLC5510IPWR uses internal 2-V referencing (REFBS shorted to REFB, REFTS shorted to REFT), whereas TLC5510A requires external 4-V referencing (REFB grounded, REFT biased to 4 V). Interchanging them without circuit modification causes incorrect full-scale calibration.
