Texas Instruments ADS5440MPFPEP

Overview

ADS5440MPFPEP from Texas Instruments is a radiation-tolerant, 13-bit, 210-MSPS analog-to-digital converter (ADC) designed for high-speed, wideband signal acquisition in military and space-grade systems. It features fully buffered differential analog inputs (2.2-VPP range), LVDS-compatible 13-bit offset-binary outputs, 5-V analog supply, and operates across –55°C to 125°C. Used in multichannel base station receivers and software-defined radio front-ends requiring high dynamic range at IF frequencies up to 400 MHz.

For engineers reviewing the ADS5440MPFPEP datasheet, ADS5440MPFPEP pinout, ADS5440MPFPEP application, or ADS5440MPFPEP equivalent, key selection criteria include SNR (69 dBc @ 100 MHz IF), SFDR (76 dBc @ 100 MHz IF), aperture jitter (150 fs RMS), latency (4 cycles), and TQFP-80 PowerPAD™ thermal performance under extended temperature stress.

Technical Context

The ADS5440MPFPEP implements a monolithic pipeline ADC architecture using Texas Instruments' BiCom3X complementary bipolar process. Conversion is triggered on the rising edge of the differential clock input, with internal track-and-hold and digital error correction enabling 13-bit resolution at 210 MSPS.

It integrates a 2.4-V internal reference, fully differential analog input buffer with 1-kΩ DC impedance and 800-MHz bandwidth, and LVDS output drivers powered by a separate 3.3-V DRVDD supply. The device supports dc-coupled or ac-coupled analog inputs and accepts either sine-wave or square-wave clock inputs with 50% duty cycle.

Key Specifications

Pinout & Package

The ADS5440MPFPEP is housed in an 80-pin HTQFP PowerPAD™ package (PFP designator) with a 7.5 mm × 7.5 mm thermal slug. The exposed thermal pad must be soldered to PCB ground plane using ≥36 thermal vias for θ_JA = 21.7°C/W (soldered, no airflow).

FAQ

What is the maximum analog input frequency supported by the ADS5440MPFPEP?

The ADS5440MPFPEP has an analog input bandwidth of 800 MHz, meaning it maintains specified AC performance-including SNR and SFDR-up to 800 MHz. At 400 MHz input frequency, the ADS5440MPFPEP delivers 65 dBc SNR and 63.3 dBc SFDR at 210 MSPS, confirming usability in UHF-band direct RF sampling applications without external anti-alias filtering.

Does the ADS5440MPFPEP require an external reference voltage?

No, the ADS5440MPFPEP includes an integrated 2.4-V reference generator that sets both the input common-mode voltage and full-scale range. This eliminates the need for external reference components and simplifies system design-particularly in space- and weight-constrained military platforms where BOM reduction is critical.

How is clock jitter performance specified for the ADS5440MPFPEP?

The ADS5440MPFPEP specifies aperture uncertainty (jitter) as 150 fs RMS over the full temperature range. This value directly impacts SNR degradation at high input frequencies and is measured under standard conditions: 210 MSPS, 50% clock duty cycle, AVDD = 5 V, DRVDD = 3.3 V, and –1-dBFS input. Lower jitter preserves ENOB above 11 bits even at 230-MHz IF.

What thermal management is required for reliable operation of the ADS5440MPFPEP?

Reliable operation of the ADS5440MPFPEP requires soldering the exposed thermal pad to a solid PCB ground plane using at least 36 thermal vias (6 × 6 array). With this layout, θ_JA is 21.7°C/W (no airflow). Without proper thermal pad connection, θ_JA degrades to 50°C/W-risking junction temperatures exceeding 150°C at full 2-W dissipation in high ambient environments.

Is the ADS5440MPFPEP pin-compatible with any other TI ADCs?

Yes, the ADS5440MPFPEP is explicitly pin-compatible with the ADS5444-TI's 250-MSPS variant in the same family. Both share identical 80-pin HTQFP PowerPAD™ packaging, pin assignments, and power sequencing requirements, enabling drop-in upgrades in existing layouts when higher sample rates are needed without board redesign.
