Product details
Overview
ADS5272IPFP from Texas Instruments is an 8-channel, 12-bit, 65MSPS analog-to-digital converter with integrated PLL, serial LVDS interface, and simultaneous sample-and-hold. It delivers 71.1dBFS SNR at 5MHz IF, operates from 3.3V analog/digital supplies, and features internal/external reference selection for portable ultrasound, optical networking, and test equipment signal acquisition.
For engineers reviewing the ADS5272IPFP datasheet, ADS5272IPFP pinout, ADS5272IPFP application, or ADS5272IPFP equivalent, key selection criteria include its 65MSPS per-channel sampling rate, serialized LVDS output architecture (12× ADCLK, 8 differential data pairs), TQFP-80 PowerPAD package thermal performance (θJC = 4.2°C/W), and support for LSB/MSB-first serial format via register control.
Technical Context
The ADS5272IPFP integrates eight independent 12-bit ADC cores, each with dedicated S/H and LVDS serializer, sharing a single ADCLK input. An on-chip PLL multiplies the input sampling clock by 12 to generate high-frequency LVDS bit clocks (up to 390MHz) and word clocks (65MHz).
It supports dual reference modes: internal (1.95V REFT / 0.95V REFB, 1.45V VCM) or external (REFT/REFB programmable within 1.825–2.0V / 0.9–1.075V), with fixed attenuation matching ≤0.2dB across channels and aperture jitter of 1ps RMS.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS5273IPFP | 70MSPS max sample rate; identical 12-bit resolution, TQFP-80 package, and LVDS interface architecture | Higher throughput suits wider IF bandwidths (e.g., 5G NR channel analysis), but consumes ~5% more power at full rate | Select ADS5273IPFP when system requires >65MSPS per channel without changing PCB layout or firmware interface |
| ADS5271IPFP | 50MSPS max sample rate; same pinout, reference architecture, and serial register map as ADS5272IPFP | Lower power (792mW internal ref) and reduced thermal load - preferred for battery-powered portable instruments with relaxed bandwidth needs | Choose ADS5271IPFP to reduce system power and simplify thermal design where 50MSPS meets signal bandwidth requirements |
Compared with ADS5272IPFP, ADS5273IPFP offers higher sampling rate for wider instantaneous bandwidth, while ADS5271IPFP trades speed for lower power and thermal density - both maintain pin-for-pin compatibility and identical register-level control.

FAQ
What is the maximum sampling rate supported by the ADS5272IPFP?
The ADS5272IPFP supports a maximum sampling rate of 65MSPS per channel. This rate is validated across all eight ADC channels simultaneously with full AC performance, including 71.1dBFS SNR at 5MHz input frequency and 89dBc SFDR. The device uses an integrated PLL to multiply the input ADCLK by 12, generating the 390MHz LVDS bit clock required for serialized 12-bit output transmission.
Does the ADS5272IPFP require an external reference voltage?
No, the ADS5272IPFP does not require an external reference voltage. It provides an internal reference (1.95V REFT / 0.95V REFB / 1.45V VCM) that delivers optimal performance, including 71.1dBFS SNR at 5MHz. External reference mode is optional and enabled by driving the INT/EXT pin low; in that mode, REFT must be 1.825–2.0V and REFB 0.9–1.075V, with VCM derived from the internal bandgap.
How many LVDS data output pairs does the ADS5272IPFP provide?
The ADS5272IPFP provides eight differential LVDS data output pairs: OUT1P/OUT1N through OUT8P/OUT8N - one pair per ADC channel. In addition, it outputs two LVDS clock pairs: ADCLKP/ADCLKN (65MHz word clock) and LCLKP/LCLKN (390MHz bit clock). All LVDS outputs operate at programmable current levels (2.5–6.0mA) to optimize signal integrity for specific PCB trace lengths and terminations.
What package type is used for the ADS5272IPFP?
The ADS5272IPFP is packaged in an HTQFP-80 PowerPAD™ (PFP) package. This thermally enhanced quad flat pack features an exposed copper thermal pad (minimum 4.69mm × 4.69mm) on the underside for direct PCB heat sinking. Its θJC of 4.2°C/W and θJA of 19.4°C/W enable reliable operation at full 983mW power dissipation within the –40°C to +85°C industrial temperature range.
Can individual ADC channels be powered down on the ADS5272IPFP?
Yes, individual ADC channels can be powered down on the ADS5272IPFP using serial register controls. Registers 2 and 3 allow independent enable/disable of channels 1–4 and 5–8 respectively via 4-bit fields (e.g., value 1010 in Register 2 powers down channels 4 and 2). This feature reduces total power consumption proportionally - disabling one channel lowers analog supply current by approximately 12%, improving thermal management in partial-bandwidth applications.
