Product details
Overview
TLV5580IDWR from Texas Instruments is an 8-bit, 80 MSPS analog-to-digital converter (ADC) optimized for high-speed digitization in graphics, communications, and medical imaging systems. It operates from a single 3.3 V supply, delivers 700 MHz analog input bandwidth, consumes 165 mW typical power with external references, and features TTL/CMOS-compatible digital I/O and three-state outputs.
For engineers reviewing the TLV5580IDWR datasheet, TLV5580IDWR pinout, TLV5580IDWR application, or TLV5580IDWR equivalent, this page provides verified functional identity, validated SOIC-28 package mapping, confirmed 4.5-cycle pipeline latency, real-world dynamic performance (ENOB ≥6.2 bits at 80 MSPS), and two technically documented alternative ADCs for IF sampling and display interface designs.
Technical Context
The TLV5580IDWR implements a single-pipeline CMOS architecture with six 2-bit ADC/DAC stages plus one final flash stage, corrected by logic that combines first-stage 2-bit output and one bit from each subsequent stage to produce a monotonic 8-bit result with no missing codes across −40°C to +85°C. Its aperture jitter is 1.5 ps rms, enabling accurate undersampling of RF/IF signals up to 76 MHz.
It supports flexible reference configuration: internal bottom/top references (REFBO/REFTO) or user-supplied external voltages at REFBI/REFTI, 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), both active-high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution & Speed | 8-bit, 80 MSPS maximum sampling rate - enables digitization of baseband video, DVD read channels, and sub-Nyquist IF signals up to 76 MHz. |
| Analog Input Bandwidth | 700 MHz typical - supports wideband signal acquisition without front-end filtering degradation in high-speed DSP front-ends. |
| Power Consumption | 165 mW typical with external references - reduces thermal load in dense PCB layouts and enables low-power operation in portable imaging systems. |
| Supply Voltages | AVDD/DVDD/DRVDD = 3.0–3.6 V - separate analog, digital, and driver supplies minimize noise coupling between domains. |
| Dynamic Performance | ENOB ≥6.2 bits at 80 MSPS (fin = 1–76 MHz); SFDR ≥48 dB - sufficient for 8-bit graphics processing and medium-fidelity communication channel digitization. |
| Reference Flexibility | Internal REFBO/REFTO outputs or external REFBI/REFTI inputs - allows full-scale range tuning (1.0–1.6 Vpp) and dc-level shifting for ac- or dc-coupled analog sources. |
| Timing Latency | Pipeline delay = 4.5 CLK cycles; output delay td(o) ≤9 ns - defines deterministic data availability timing for synchronous FPGA or DSP capture logic. |
Pinout & Package
TLV5580IDWR is housed in a 28-pin SOIC (DW) package with gull-wing leads, rated for −40°C to +85°C operation. Pin spacing is 1.27 mm, body width 7.5 mm, and total package dimensions 17.9 × 7.5 × 2.35 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN (26) | Analog input | Single-ended voltage input referenced to AVSS; requires ≤80 Ω source impedance for full 700 MHz bandwidth. |
| CLK (12) | Sampling clock input | Rising-edge triggered; 12.5 ns minimum period (80 MHz max); low-jitter (<1.5 ps rms) critical for ENOB preservation. |
| D0–D7 (2–9) | Digital output data | MSB-aligned parallel output (D7 = MSB); three-state controlled by OE; 3.3 V TTL/CMOS compatible; load ≤10 pF recommended. |
| OE (13) | Output enable | Active-high; asynchronous control; 5–8 ns disable/enable timing; used for bus sharing or power-gated data capture. |
| STBY (15) | Standby mode control | Active-high; reduces power to ~15 mW; preserves register state; exits in <1 µs upon deassertion. |
| PWDN_REF (24) | Reference power-down | Active-high; disables internal REFBO/REFTO generators independently; saves ~48 mW when external references are used. |
| REFBI (21), REFTI (20) | External reference inputs | Define bottom/top of ADC transfer function; support adjustable full-scale range (e.g., 1.3 Vpp at AVDD = 3.3 V). |
| REFBO (22), REFTO (19) | Internal reference outputs | Provide factory-trimmed bottom/top references (~1.15 V and ~2.15 V at AVDD = 3.3 V); require 1 µF decoupling to AVSS. |
Key Features
| Feature | Design Value |
|---|---|
| Single-pipeline 8-bit architecture | Guarantees no missing codes over −40°C to +85°C via correction logic combining multi-stage quantization results. |
| Independent reference power-down | PWDN_REF pin disables internal REFBO/REFTO while keeping core ADC active - enables precise power optimization in mixed-reference systems. |
| Separate DRVDD supply | 3 V DRVDD (vs. 3.3 V DVDD/AVDD) reduces digital switching noise coupling into analog section, improving SFDR by ~2 dB. |
| High analog input bandwidth | 700 MHz typical - supports direct digitization of NTSC/PAL chroma, DMD/LCD panel drive signals, and IF bands without image-reject filtering. |
| Flexible reference configuration | Supports internal (REFBO/REFTO), external (REFBI/REFTI), or hybrid reference topologies - enables dc-coupled, ac-coupled, and bipolar input designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed 8-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS820U | 8-bit, 20 MSPS; 250 MHz input bandwidth; single +5 V supply; no internal references; 24-pin SOIC. | Limited to lower-frequency video and instrumentation; lacks reference flexibility and IF undersampling capability. | Select when cost sensitivity outweighs speed requirements and system already uses +5 V rails. |
| MAX1186ECM+ | 8-bit, 65 MSPS; 500 MHz input bandwidth; 3.3 V supply; internal references only; 28-pin SSOP. | Lower ENOB (5.9 bits at 65 MSPS); no external reference inputs; narrower bandwidth limits IF sampling fidelity. | Choose for space-constrained designs where TSSOP footprint is preferred and 700 MHz bandwidth is not required. |
Compared with TLV5580IDWR, ADS820U trades 4× lower speed and no reference configurability for legacy +5 V compatibility, while MAX1186ECM+ offers smaller SSOP packaging but sacrifices 200 MHz bandwidth and external reference control-critical for adaptive full-scale range in DVD and medical systems.

FAQ
What is the operating temperature range for TLV5580IDWR?
The TLV5580IDWR is specified for −40°C to +85°C ambient operation, matching the Industrial temperature grade indicated by the "I" suffix in the part number. This range is validated across all electrical parameters including INL (±2.4 LSB), ENOB (≥6.2 bits), and power consumption (165 mW typ) with external references.
Does TLV5580IDWR support external voltage references?
Yes, TLV5580IDWR supports external references via REFBI (pin 21) and REFTI (pin 20), enabling full-scale range adjustment from 1.0 Vpp to 1.6 Vpp depending on AVDD. When external references are applied, internal REFBO and REFTO can be disabled using PWDN_REF (pin 24) to reduce power by ~48 mW.
What is the pipeline latency of TLV5580IDWR?
The TLV5580IDWR has a fixed pipeline latency of 4.5 clock cycles, meaning the digital output corresponding to sample N appears 4.5 CLK periods after the rising edge that initiated that sample. This value is constant regardless of clock frequency and is critical for synchronizing FPGA capture logic with output data valid windows.
Can TLV5580IDWR be used for undersampling applications?
Yes, TLV5580IDWR is explicitly suited for undersampling due to its 700 MHz analog input bandwidth and low aperture jitter (1.5 ps rms). It has been validated for IF sampling up to 76 MHz at 80 MSPS, making it appropriate for digitizing satellite tuner IF outputs and ultrasound echo signals without anti-alias filtering.
What package type does TLV5580IDWR use?
TLV5580IDWR uses a 28-pin SOIC (DW) package with standard gull-wing leads, 1.27 mm pitch, and 7.5 mm body width. This package is RoHS-compliant, tape-and-reel packaged (1000 units per reel), and rated for −40°C to +85°C operation per the "I" temperature grade designation.
