Texas Instruments TLV5580CPW

Overview

TLV5580CPW 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, and features 3.3 V TTL/CMOS-compatible digital I/O. It is used in IF-sampling communication receivers and LCD/DMD projection interfaces.

For engineers reviewing the TLV5580CPW datasheet, TLV5580CPW pinout, TLV5580CPW application, or TLV5580CPW equivalent, key selection considerations include its 80 MSPS sampling rate with 6.7-bit ENOB at 1 MHz, external reference flexibility, 4.5-clock-cycle pipeline latency, and TSSOP-28 package compatibility with high-density PCB layouts.

Technical Context

The TLV5580CPW implements a single-pipeline CMOS architecture with six 2-bit ADC/DAC stages plus one final flash stage, corrected by logic that combines bits across all stages to produce a monotonic 8-bit output with no missing codes over temperature. Its aperture jitter is 1.5 ps rms, enabling accurate undersampling of RF signals up to 76 MHz.

It supports both internal and externally adjustable voltage references - REFBI and REFTI define the bottom and top reference levels, allowing full-scale range tuning from 1.0 Vpp to 1.6 Vpp depending on AVDD. The device includes independent power-down control for references (PWDN_REF) and standby mode (STBY), reducing power to 11–15 mW.

Key Specifications

Pinout & Package

TLV5580CPW is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP), with pin 1 marked by a dot. 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 TLV5580CPW?

The TLV5580CPW supports a maximum sampling rate of 80 MSPS, with a minimum conversion rate of 10 kHz. At 80 MSPS, it achieves 6.7-bit effective number of bits (ENOB) at 1 MHz input frequency and maintains 700 MHz analog input bandwidth - enabling direct IF sampling in communication systems without downconversion stages.

Does the TLV5580CPW require external voltage references to operate?

No, the TLV5580CPW does not require external voltage references. It includes internal bottom (REFBO) and top (REFTO) reference outputs that can be connected directly to REFBI and REFTI pins. However, external references may be applied to adjust full-scale range from 1.0 Vpp to 1.6 Vpp - and PWDN_REF can independently disable internal references to save power when externals are used.

What is the pipeline latency of the TLV5580CPW, and how does it affect system timing?

The TLV5580CPW has a fixed pipeline latency of 4.5 clock cycles. This means the first valid digital output appears 4.5 CLK periods after the corresponding analog sample is taken. When combined with output buffer delay (up to 9 ns), system designers must account for total latency to synchronize with downstream logic - especially critical in closed-loop DSP front-ends like TMS320C6000-based systems.

Can the TLV5580CPW be used with a 5 V digital interface?

No, the TLV5580CPW is strictly a 3.3 V device: its digital I/O (D0–D7, CLK, OE, STBY, PWDN_REF) is TTL/CMOS-compatible only at 3.3 V levels, with VIH(min) = 2.0 V and VOL(max) = 0.1 V at 3.6 V supply. Interfacing to 5 V logic requires level-shifting circuitry - direct connection risks damage and violates absolute maximum ratings.

How does the TLV5580CPW manage power consumption in standby mode?

In standby mode (STBY = high), the TLV5580CPW reduces total power dissipation to 11–15 mW while retaining configuration and reference states. This is distinct from PWDN_REF, which only disables internal reference generation (saving ~48 mW). Standby mode is ideal for burst-mode acquisition systems where the ADC must wake rapidly without reinitialization.
