Texas Instruments ADS5411IPJYR

Overview

ADS5411IPJYR from Texas Instruments is an 11-bit, 105 MSPS pipeline analog-to-digital converter (ADC) operating from a 5 V analog supply and delivering 3.3 V CMOS-compatible parallel digital outputs. It features 2.2 V_PP differential input range, 66.4 dBc SNR at 50 MHz IF, and 90 dBc SFDR at 105 MSPS - optimized for high-intercept, wideband IF sampling in communications receivers.

For engineers reviewing the ADS5411IPJYR datasheet, ADS5411IPJYR pinout, ADS5411IPJYR application, or ADS5411IPJYR equivalent, this page delivers verified electrical specs, thermal behavior, timing constraints, package layout, and real-world interface guidance - all validated against TI's SLAS487A (Jan 2010) production data sheet.

Technical Context

The ADS5411IPJYR implements a 3-stage bipolar pipeline architecture on TI's BiCom3 process, using both clock edges to achieve 105 MSPS throughput with 3-cycle latency. Its on-chip track-and-hold isolates the analog source from internal switching noise, while integrated reference generation fixes V_CM at 2.4 V and sets 1 kΩ differential input impedance.

Digital output drivers are powered separately via DRVDD (3.0–3.6 V), enabling direct interfacing with 3.3 V logic without level shifters. Clock inputs accept either differential sine-wave (1–5 V_PP) or single-ended signals, with aperture jitter specified at 150 fs RMS and slope-dependent jitter factor of 50 µV.

Key Specifications

Pinout & Package

ADS5411IPJYR is housed in a 52-pin HTQFP package (PJY suffix) with exposed thermal pad (PowerPad™) for enhanced heat dissipation. Thermal resistance θ_JA is 22.5°C/W with soldered slug and no airflow.

FAQ

What is the absolute maximum clock voltage rating for ADS5411IPJYR?

The ADS5411IPJYR specifies ±2.5 V differential voltage between CLK and CLK pins, with absolute maximum analog input voltage ranging from −0.3 V to AVDD + 0.3 V (i.e., −0.3 V to +5.3 V). Exceeding these limits risks permanent damage per TI's SLAS487A absolute maximum ratings table.

Does ADS5411IPJYR support single-ended clock input?

Yes, ADS5411IPJYR supports single-ended clock drive: connect CLK (pin 5) via 0.01 µF AC coupling to the source, and tie CLK (pin 6) to ground through a 0.01 µF capacitor. Performance remains within spec versus differential mode, though jitter-sensitive applications benefit from differential routing.

What is the purpose of the DMID pin on ADS5411IPJYR?

The DMID pin on ADS5411IPJYR provides a stable voltage reference at approximately DRVDD/2 (1.65 V nominal) to terminate the parallel digital bus. This reduces ground bounce, improves signal integrity, and ensures consistent setup/hold timing margins for interfacing with 3.3 V FPGA or ASIC inputs.

How is the analog input common-mode voltage set in ADS5411IPJYR?

ADS5411IPJYR internally sets analog input common-mode voltage to 2.4 V using on-chip 500 Ω resistors tied to VREF. This eliminates need for external bias networks and ensures consistent 2.2 V_PP full-scale swing (±0.55 V around 2.4 V) across temperature and process variation.

What thermal guidelines apply to ADS5411IPJYR's PowerPad package?

ADS5411IPJYR's HTQFP package requires soldering the exposed PowerPad to a minimum 1 cm² copper pour with ≥25 thermal vias (5×5 array) for θ_JA = 22.5°C/W. Without soldered slug, θ_JA degrades to 33.3°C/W - potentially exceeding 150°C junction limit at full 1.9 W dissipation.
