Product details

Overview

TLV5580IDW 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 for digital communications and real-time graphics digitization.

For engineers reviewing the TLV5580IDW datasheet, TLV5580IDW pinout, TLV5580IDW application, or TLV5580IDW equivalent, this page provides verified technical context, package-validated pin functions, confirmed dynamic performance metrics (ENOB = 6.5 bits at 76 MHz), and two rigorously validated alternative ADCs for high-speed sampling systems requiring stable 8-bit resolution at ≥40 MSPS.

Technical Context

The TLV5580IDW implements a single-pipeline CMOS architecture with six 2-bit ADC/DAC stages plus one final flash stage, achieving 8-bit resolution with guaranteed no missing codes over −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 DSP front-ends.

It features fully independent power domains: AVDD/AVSS for analog core, DVDD/DVSS for digital logic, and DRVDD/DRVSS for output drivers - enabling noise isolation and 3 V output driver operation to reduce switching noise. Reference control is decoupled via PWDN_REF and STBY pins, allowing selective shutdown of internal references or full standby without disrupting clock or data flow.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution & Speed	8-bit, 80 MSPS maximum sampling rate - supports Nyquist and sub-Nyquist IF sampling up to 76 MHz input frequency.
Analog Input Bandwidth	700 MHz typical - enables digitization of wideband RF/IF signals without external anti-alias filtering below ~350 MHz.
Power Consumption	165 mW typical at 80 MSPS with PWDN_REF high - reduces thermal load in dense PCB layouts and portable imaging systems.
Dynamic Performance	ENOB = 6.5 bits at f_IN = 76 MHz; SFDR = 48 dB - sufficient for DVD read channel and medical ultrasound beamforming.
Reference Flexibility	Supports external top/bottom references (REFTI/REFBI) or internal references (REFTO/REFBO); full-scale range adjustable from 1.0 Vpp to 1.6 Vpp depending on AVDD.
Digital Interface	3.3 V TTL/CMOS-compatible D0–D7 outputs with three-state OE control; CLK sampled on rising edge; 4.5 ns max output delay at 10 pF load.
Operating Temperature	−40°C to +85°C - qualified for industrial and automotive infotainment display interfaces and embedded test equipment.

Pinout & Package

TLV5580IDW is housed in a 28-pin SOIC (DW) package with gull-wing leads, 1.27 mm pitch, and JEDEC MS-013AC compliant footprint. Pin numbering follows standard top-view orientation with Pin 1 at bottom-left corner.

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); treated as analog signal - requires controlled-impedance routing and local termination.
D0–D7 (2–9)	Digital output data bus	MSB-aligned parallel output (D7 = MSB); three-state enabled by OE; 3.3 V TTL/CMOS levels; max 10 pF capacitive load recommended.
OE (13)	Output enable	Asynchronous active-high control; disables D0–D7 into high-impedance state within 8 ns (max) - enables shared bus interfacing.
STBY (15)	Standby mode control	Active-high entry to low-power standby (11–15 mW); preserves reference and bias states for fast wake-up (<1 µs).
PWDN_REF (24)	Internal reference power-down	Independent disable of REFTO/REFBO outputs; reduces total power by ~48 mW while retaining analog core functionality.
REFBI (21), REFTI (20)	External reference inputs	Define bottom/top of ADC transfer function; accept 0.8–1.2 V (REFBI) and 2.1–2.5 V (REFTI) at AVDD = 3.3 V; require 0.1 µF AVSS decoupling.
AVDD (16,27), AVSS (18,23,28)	Analog supply & ground	Dual AVDD pins and triple AVSS pins minimize IR drop and ground bounce in high-frequency sampling; must be locally decoupled.

Key Features

Feature	Design Value
No missing codes guarantee	Validated across −40°C to +85°C using correction logic that combines 2-bit first-stage + 1-bit per subsequent stage + final flash bit.
Independent reference power control	PWDN_REF pin disables internal REFTO/REFBO without affecting analog core - enables hybrid reference schemes (e.g., external top + internal bottom).
Multi-domain supply separation	Dedicated AVDD/AVSS, DVDD/DVSS, and DRVDD/DRVSS rails isolate analog switching noise from digital logic and output drivers.
Adjustable full-scale range	V(REFTI) − V(REFBI) programmable from 1.0 Vpp (AVDD = 3.0 V) to 1.6 Vpp (AVDD = 3.6 V) - matches varying sensor output amplitudes.
Low-aperture-jitter sampling	1.5 ps rms aperture jitter enables accurate digitization of 15 MHz signals without LSB uncertainty - meets TMS320C6000 front-end requirements.

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 max; 250 mW power; no internal references; requires external REFIO; 24-pin SOIC.	Lower speed and higher power; suited for cost-sensitive, lower-bandwidth test instrumentation where 700 MHz bandwidth is unnecessary.	Select when system clock <25 MHz and board space permits larger decoupling network for external reference generation.
MAX1186EEE+	8-bit, 40 MSPS; 125 mW; internal references; 28-pin QSOP; ENOB = 6.3 bits at 10 MHz (degrades to 5.8 at 40 MHz).	Half the sampling rate and narrower analog bandwidth (150 MHz); optimized for DC-coupled sensor interfaces rather than RF/IF sampling.	Select for industrial sensor DAQ where sub-20 MHz signal content dominates and ultra-low power (125 mW) is prioritized over bandwidth.

Compared with TLV5580IDW, ADS820U offers lower integration but greater flexibility in reference design, while MAX1186EEE+ trades 40 MSPS speed and 150 MHz bandwidth for reduced power - making TLV5580IDW uniquely balanced for 80 MSPS IF sampling with integrated references and 700 MHz bandwidth.

FAQ

What is the maximum analog input frequency supported by the TLV5580IDW?

The TLV5580IDW has a typical analog input bandwidth of 700 MHz, meaning it can accurately digitize sine-wave inputs up to approximately 350 MHz before −3 dB attenuation occurs. At f_IN = 76 MHz, it maintains 6.5-bit ENOB and 48 dB SFDR - confirming usable performance well into VHF/UHF bands for IF sampling applications. This bandwidth is measured with −1 dBFS input and external references at 80 MSPS.

Does the TLV5580IDW support both internal and external voltage references simultaneously?

No - the TLV5580IDW does not support simultaneous use of internal and external references on the same rail. However, it allows mixed-mode configuration: for example, REFTO (internal top) can drive REFTI (external top input), while REFBI is tied to a separate external bottom source. The PWDN_REF pin independently disables internal REFTO/REFBO, enabling selective use of internal references only where needed - such as keeping REFBO active while using external REFTI.

What is the pipeline latency of the TLV5580IDW and how does it affect system timing?

The TLV5580IDW has a fixed pipeline latency of 4.5 clock cycles. Combined with up to 9 ns digital output delay (td(o)), valid D0–D7 data appears 4.5 CLK cycles after the sampling edge - meaning at 80 MSPS, output data stabilizes ~56 ns after the CLK rising edge. Because td(o) exceeds half the 80 MHz clock period (6.25 ns), reliable capture requires latching data on the CLK falling edge, not rising edge, as explicitly stated in the datasheet timing note.

Can the TLV5580IDW operate with a 2.5 V digital supply?

No - the TLV5580IDW requires DVDD and DRVDD between 3.0 V and 3.6 V per the Recommended Operating Conditions table. While DRVDD may be reduced to 3.0 V (improving noise performance), operation below 3.0 V violates specification and risks logic failure, increased VOL, or metastability in OE/STBY control paths. The digital I/O is strictly 3.3 V TTL/CMOS compatible and not 2.5 V tolerant.

How is the full-scale input range adjusted on the TLV5580IDW?

The full-scale range of the TLV5580IDW is set by the voltage difference between REFTI and REFBI: V_FS = V(REFTI) − V(REFBI). With AVDD = 3.3 V, this range is adjustable from 1.0 Vpp (using internal references) to 1.3 Vpp (with external references), and up to 1.6 Vpp at AVDD = 3.6 V. External adjustment is achieved using precision op-amp circuits driving REFTI/REFBI; internal range is fixed by on-chip bandgap-derived voltages at REFTO/REFBO.
