Replacement verdict
Not a drop-in replacement
The ADS5474IPFP and ADS5413IPHP are not drop-in replacements for one another. They differ in resolution, sampling rate, analog input architecture, and digital output interface, so a direct board-level substitution is not feasible without redesign of the signal chain, clocking, and digital interface.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5474IPFP | ADS5413IPHP | Why it matters |
|---|---|---|---|
| Resolution | 14 bit | 12 bit | Resolution determines the number of discrete levels the ADC can represent; a 14-bit device provides 4x finer quantization than a 12-bit device, directly affecting achievable SNR and dynamic range. |
| Sampling Rate | 400 MSPS | 65 MSPS | Maximum sample rate defines the input bandwidth the ADC can digitize; the ADS5474 supports much higher-frequency signals and wider Nyquist zones than the ADS5413. |
| Input Type | Differential | Differential | Both use differential inputs, which reject common-mode noise and improve distortion performance; matching input topology simplifies analog front-end reuse. |
| Supply Voltage | 3.3 V analog / 3.3 V digital | 3.3 V analog / 3.3 V digital | Compatible supply rails allow the same power architecture to be reused, though current draw and internal biasing differ between the two devices. |
| Output Interface | Parallel LVDS | Parallel CMOS | The output signaling standard dictates the digital receiver design; LVDS offers lower EMI and higher speed, while CMOS is simpler but limited in rate and drive distance. |
| Package | 80-pin HTQFP (PFP) | 48-pin HTQFP (PHP) | Package footprint and pin count affect PCB layout and cannot be interchanged without a board redesign; the two parts are not drop-in compatible. |
| Power Consumption | Approx. 2.2 W | Approx. 0.35 W | Power dissipation impacts thermal design and supply sizing; the high-speed ADS5474 consumes significantly more power than the lower-rate ADS5413. |
| SFDR / SNR Performance Class | High-speed, high-SNR (approx. 69 dB SNR) | Moderate-speed (approx. 64 dB SNR) | Dynamic performance metrics determine suitability for demanding signal chains; the ADS5474 targets wideband high-dynamic-range applications while the ADS5413 targets lower-rate systems. |

Frequently asked questions
What are the key differences between the ADS5474IPFP and ADS5413IPHP?
The ADS5474IPFP is a 14-bit, 400-MSPS analog-to-digital converter in a 80-pin HTQFP package, while the ADS5413IPHP is a 12-bit, 65-MSPS ADC in a 48-pin HTQFP package. The ADS5474IPFP offers higher resolution and a significantly faster sampling rate, whereas the ADS5413IPHP targets lower-speed, lower-resolution applications.
Are the ADS5474IPFP and ADS5413IPHP pin-compatible?
No. The ADS5474IPFP uses an 80-pin HTQFP package and the ADS5413IPHP uses a 48-pin HTQFP package, so they have different pin counts, pin functions, and PCB land patterns and are not directly interchangeable.
What are the maximum sampling rates of these two ADCs?
The ADS5474IPFP supports a maximum sampling rate of 400 MSPS, while the ADS5413IPHP supports a maximum sampling rate of 65 MSPS.
What resolution does each converter provide?
The ADS5474IPFP provides 14-bit resolution, and the ADS5413IPHP provides 12-bit resolution.
What input interface and output format do these ADCs use?
Both devices accept differential analog inputs and provide parallel LVDS-compatible digital output data, as specified in their respective manufacturer datasheets.
Can the ADS5413IPHP be used as a drop-in replacement for the ADS5474IPFP?
No. The two devices differ in resolution, sampling rate, package size, and pinout, so the ADS5413IPHP cannot be used as a drop-in replacement for the ADS5474IPFP without a complete redesign and validation against the target application requirements.
What are typical applications for each device?
The ADS5474IPFP, with its 14-bit resolution and 400-MSPS sampling rate, is suited to high-speed signal acquisition such as communications receivers, test and measurement, and medical imaging. The ADS5413IPHP, with 12-bit resolution and 65-MSPS sampling, is suited to lower-speed digitization such as industrial instrumentation and general-purpose data acquisition.
