Texas Instruments TLV5580CPWR

Overview

TLV5580CPWR from Texas Instruments is an 8-bit, 80 MSPS analog-to-digital converter (ADC) designed for high-speed digitization in signal acquisition front-ends. It operates from a single 3.3 V supply, delivers 165 mW typical power consumption with external references, supports 700 MHz analog input bandwidth, and features TTL/CMOS-compatible 3.3 V digital I/O. It is used in IF-sampling communication receivers and LCD/DMD projection interface circuits.

For engineers reviewing the TLV5580CPWR datasheet, TLV5580CPWR pinout, TLV5580CPWR application, or TLV5580CPWR equivalent, key selection considerations include its 80 MSPS sampling rate with 6.7-bit ENOB at 1 MHz, 4.5-clock-cycle pipeline latency, external reference flexibility, and TSSOP-28 package compatibility with high-density PCB layouts.

Technical Context

The TLV5580CPWR implements a single-pipeline CMOS architecture with six 2-bit ADC/DAC stages plus one final flash stage, corrected by logic that combines outputs to yield full 8-bit resolution without missing codes across temperature. Its aperture jitter is 1.5 ps RMS, enabling accurate undersampling of RF/IF signals up to 76 MHz.

It supports both internal and externally supplied reference voltages via dedicated REFTI/REFBI inputs and REFTO/REFBO outputs, allowing full-scale range adjustment from 1.0 Vpp to 1.6 Vpp depending on AVDD. The device includes independent power-down control for references (PWDN_REF) and full standby mode (STBY), with three-state digital outputs enabled by OE.

Key Specifications

Pinout & Package

TLV5580CPWR is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP), with pin 1 marked by a dot or beveled corner. Analog, digital, and driver power domains are physically separated across the package to minimize noise coupling.

FAQ

What is the maximum sampling rate supported by the TLV5580CPWR?

The TLV5580CPWR supports a maximum sampling rate of 80 MSPS, as specified under recommended operating conditions with fCLK = 80 MHz and proper decoupling. At this rate, it maintains 6.7-bit effective number of bits (ENOB) at 1 MHz input frequency and meets all dynamic performance specifications including SFDR ≥48 dB. Operation below 10 kHz is also supported for low-speed applications.

Does the TLV5580CPWR require external voltage references to operate?

No, the TLV5580CPWR does not require external voltage references. It includes internal bottom and top reference generators accessible via REFBO and REFTO pins. However, using external references (applied to REFBI and REFTI) extends the full-scale input range from 1.0 Vpp (internal) to up to 1.6 Vpp and reduces power consumption by enabling PWDN_REF to disable internal references.

What package type is used for the TLV5580CPWR?

The TLV5580CPWR uses a 28-pin Thin Shrink Small Outline Package (TSSOP), identified by package designator PW. This surface-mount package measures 9.7 mm × 4.4 mm with 0.65 mm lead pitch and is RoHS-compliant. It is distinct from the SOIC-28 (DW) variant and requires specific footprint and reflow profile validation.

How does the pipeline latency of the TLV5580CPWR affect system timing?

The TLV5580CPWR has a fixed pipeline latency of 4.5 clock cycles, meaning the digital output corresponding to a given analog sample appears 4.5 CLK periods after sampling begins. When combined with up to 9 ns output delay (td(o)), this determines total system latency and dictates that output data must be latched on the falling edge of CLK at 80 MSPS to ensure setup/hold compliance.

Can the TLV5580CPWR be used for undersampling applications?

Yes, the TLV5580CPWR is explicitly suited for undersampling due to its 700 MHz analog input bandwidth and low aperture jitter (1.5 ps RMS). It supports reliable digitization of IF signals up to 76 MHz using sub-Nyquist sampling methods, as confirmed in the datasheet's description of communication system IF sampling and spectral plots showing folded input spectra.
