Replacement verdict
Not a drop-in replacement
The ADS5400IPZP and ADS5411IPGPR are not drop-in replacements for one another. They differ in resolution, sampling rate, package and pinout, and analog input architecture, so a direct board-level substitution is not possible without redesign and revalidation.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5400IPZP | ADS5411IPGPR | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 11 bit | Resolution determines the quantization granularity and achievable SNR; a 12-bit ADC provides finer amplitude detail than an 11-bit device. |
| Sampling Rate | 1 GSPS | 105 MSPS | Maximum sample rate defines the input bandwidth and Nyquist zone the converter can support; these parts target very different signal bandwidths. |
| Input Type | Differential | Differential | Differential inputs improve common-mode rejection and dynamic performance; both parts use differential analog inputs. |
| Output Interface | LVDS (DDR) | LVDS (DDR) | The digital output format must match the receiving FPGA/ASIC interface; both use double-data-rate LVDS. |
| Supply Voltage | 3.3 V analog / 1.8 V digital | 3.3 V analog / 1.8 V digital | Supply rails must be compatible with the board power tree; both require 3.3 V analog and 1.8 V digital supplies. |
| Package | 100-pin HTQFP (PZP) | 80-pin HTQFP (PGP) | Package footprint and pinout determine PCB layout compatibility; different packages are not drop-in interchangeable. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Industrial temperature range ensures reliable operation across the same environmental conditions for both parts. |
| Power Consumption (typical) | ~2.4 W | ~1.0 W | Power dissipation affects thermal design and supply sizing; the higher-speed ADS5400 consumes substantially more power. |

Frequently asked questions
What are the key differences between the ADS5400IPZP and ADS5411IPGPR?
The ADS5400IPZP is a 12-bit, 1-GSPS analog-to-digital converter in a 100-pin HTQFP (PZP) package, while the ADS5411IPGPR is an 11-bit, 105-MSPS ADC in a 52-pin HTQFP (PGP) package. They differ in resolution, sampling rate, package footprint, and pin count, so they are not drop-in replacements for each other.
Do the ADS5400IPZP and ADS5411IPGPR have compatible packages and pinouts?
No. The ADS5400IPZP uses a 100-pin HTQFP (PZP) package, and the ADS5411IPGPR uses a 52-pin HTQFP (PGP) package. The pin counts and package body sizes differ, so the PCB land patterns and pin functions are not interchangeable.
What are the maximum sampling rates of these two ADCs?
The ADS5400IPZP supports a maximum sampling rate of 1 GSPS (1,000 MSPS), while the ADS5411IPGPR supports a maximum sampling rate of 105 MSPS. The ADS5400 is intended for much higher-speed signal acquisition applications.
What resolution does each converter provide?
The ADS5400IPZP provides 12-bit resolution, and the ADS5411IPGPR provides 11-bit resolution. The one-bit difference affects achievable SNR and quantization noise in the target design.
Are the ADS5400IPZP and ADS5411IPGPR pin-to-pin or functionally interchangeable?
No. Because they differ in resolution, sampling rate, package pin count, and pinout, they cannot be treated as pin-to-pin or functional equivalents. Any substitution requires full validation against the respective manufacturer datasheets and the target design requirements.
What input and output interface types do these ADCs use?
The ADS5400IPZP provides a differential analog input and a parallel LVDS-compatible digital output interface. The ADS5411IPGPR also uses a differential analog input with a parallel CMOS-compatible output interface. Interface compatibility should be confirmed against the official datasheets before design reuse.
Which applications suit the ADS5400IPZP versus the ADS5411IPGPR?
The ADS5400IPZP, with 12-bit resolution at up to 1 GSPS, suits high-speed digitizers, wideband communications receivers, and test instrumentation. The ADS5411IPGPR, with 11-bit resolution at up to 105 MSPS, suits lower-speed data acquisition, medical imaging, and general-purpose signal processing where a 1-GSPS converter is unnecessary.
