Texas Instruments TLV5580IPW

Overview

TLV5580IPW from Texas Instruments is an 8-bit, 80 MSPS analog-to-digital converter (ADC) designed for high-speed digitization in signal acquisition paths. It operates from a single 3.3 V supply, delivers 700 MHz analog input bandwidth, consumes 165 mW typical power in active mode, and supports external or internal voltage references with adjustable full-scale range up to 1.6 Vpp. It is used in IF-sampling communication receivers and LCD/DMD projection interfaces.

For engineers reviewing the TLV5580IPW datasheet, TLV5580IPW pinout, TLV5580IPW application, or TLV5580IPW equivalent, key selection criteria include sampling rate vs. dynamic performance trade-offs, reference configuration flexibility, power-down control granularity (separate PWDN_REF and STBY), and compatibility with 3.3 V TTL/CMOS digital interfaces in high-speed DSP front-ends.

Technical Context

The TLV5580IPW 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 monotonic 8-bit results with no missing codes across −40°C to +85°C. Its aperture jitter is 1.5 ps rms, and pipeline latency is fixed at 4.5 clock cycles - critical for deterministic timing in real-time sampling systems.

Digital I/O uses 3.3 V TTL/CMOS levels with three-state outputs controlled by OE; analog inputs accept dc- or ac-coupled signals with 4 pF input capacitance and require source impedance ≤80 Ω at 80 MSPS. Reference flexibility includes independent top/bottom external inputs (REFTI/REFBI) or internal outputs (REFTO/REFBO), enabling full-scale range adjustment from 1.0 Vpp to 1.6 Vpp depending on AVDD.

Key Specifications

Pinout & Package

TLV5580IPW is housed in a 28-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad, optimized for thermal dissipation and high-density routing. Pin numbering follows standard top-view orientation with pin 1 at bottom-left corner.

FAQ

What is the operating temperature range for the TLV5580IPW?

The TLV5580IPW is rated for −40°C to +85°C ambient operation, matching the "I" grade designation in TI's ordering nomenclature. This range is validated across all electrical specifications including INL, DNL, ENOB, and power consumption - making TLV5580IPW suitable for industrial and automotive-adjacent applications where thermal stability is critical.

Does the TLV5580IPW support both internal and external voltage references simultaneously?

No - the TLV5580IPW does not operate with mixed reference modes. When external voltages are applied to REFTI and REFBI, the internal reference generator (REFTO/REFBO) must be disabled via PWDN_REF = high to avoid contention and ensure accuracy. The device supports either fully internal or fully external reference configuration, not hybrid use.

How does the pipeline latency of the TLV5580IPW affect system timing design?

The TLV5580IPW has a fixed pipeline delay of 4.5 clock cycles, meaning the first valid output corresponds to the sample taken 4.5 clocks earlier. Combined with output delay td(o) up to 9 ns, this requires careful synchronization - especially at 80 MSPS, where data must be latched on the falling edge of CLK due to timing margins. System designers must account for this deterministic latency in FPGA or DSP firmware.

Can the TLV5580IPW be used with a 5 V digital interface?

No - the TLV5580IPW digital I/O (D0–D7, CLK, OE, STBY, PWDN_REF) is strictly 3.3 V TTL/CMOS-compatible, with absolute maximum input voltage of DVDD + 0.5 V. Applying 5 V violates the 4.5 V absolute max rating and risks permanent damage. Level-shifting circuitry is required for interfacing with 5 V systems.

What decoupling is recommended for the TLV5580IPW AVDD and DRVDD supplies?

TI recommends 1 µF ceramic + 0.1 µF ceramic capacitors placed as close as possible to each AVDD pin (16, 27) and DRVDD pin (1), referenced to their respective ground pins (AVSS/DRVSS). Additional bulk capacitance (e.g., 10 µF tantalum) may be added near the power entry point. This decoupling strategy suppresses high-frequency transients from the switched-capacitor sampling core and digital output drivers.
