Replacement verdict
Not a drop-in replacement
The ADS5400IPZP and ADS5413IPHP are not drop-in replacements for one another. They differ in resolution, sampling rate, channel count, and package footprint, so a direct board-level substitution is not feasible without redesign.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5400IPZP | ADS5413IPHP | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Bit depth determines the quantization granularity and achievable SNR of the converter; matching resolution supports similar dynamic range. |
| Sampling Rate | 1 GSPS | 500 MSPS | Maximum sample rate defines the input bandwidth and Nyquist zone the ADC can support; a 2x difference affects signal capture capability. |
| Number of Input Channels | 1 | 1 | Channel count determines how many independent signals can be digitized simultaneously; both are single-channel devices. |
| 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 design; identical rails simplify substitution. |
| Analog Input Bandwidth | 2.1 GHz | 1.5 GHz | Input bandwidth limits the highest frequency that can be accurately sampled; a wider bandwidth supports higher IF sampling. |
| Package | 100-pin HTQFP (PZP) | 48-pin HTQFP (PHP) | Package footprint and pin count must match the PCB layout; different packages are not drop-in compatible. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Industrial temperature range ensures reliable operation across the same environmental conditions. |
| Power Consumption | 2.4 W (typical) | 1.2 W (typical) | Power dissipation affects thermal design and supply sizing; the higher-rate device consumes roughly twice the power. |

Frequently asked questions
What are the key differences between the ADS5400IPZP and ADS5413IPHP?
The ADS5400IPZP is a 12-bit, 1-GSPS analog-to-digital converter in a 100-pin HTQFP (PZP) package, while the ADS5413IPHP is a 12-bit, 65-MSPS ADC in a 48-pin HTQFP (PHP) package. The ADS5400 targets high-speed wideband sampling applications, whereas the ADS5413 is intended for lower-speed signal acquisition with lower power consumption.
Are the ADS5400IPZP and ADS5413IPHP pin-to-pin compatible?
No. The ADS5400IPZP uses a 100-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 cannot be treated as drop-in replacements.
What are the maximum sampling rates of these two ADCs?
The ADS5400IPZP supports a maximum sampling rate of 1 GSPS (1000 MSPS), while the ADS5413IPHP supports a maximum sampling rate of 65 MSPS. The sampling-rate difference is the primary reason the two devices serve different application classes.
Do both devices offer 12-bit resolution?
Yes. Both the ADS5400IPZP and the ADS5413IPHP are 12-bit resolution analog-to-digital converters, so resolution alone does not distinguish them; sampling rate, package, power, and interface characteristics do.
What output interface does the ADS5400IPZP provide?
The ADS5400IPZP provides a parallel LVDS-compatible output interface for its 12-bit data, suited to high-speed capture by FPGAs or ASICs. Designers should confirm the exact output timing and format against the TI datasheet before layout.
Can the ADS5413IPHP be used as a lower-cost substitute for the ADS5400IPZP?
No, not as a direct substitute. Although both are 12-bit ADCs, the ADS5413IPHP is limited to 65 MSPS versus 1 GSPS for the ADS5400IPZP and uses a different 48-pin package, so any substitution would require a full redesign and validation of sampling performance, interface timing, and PCB layout.
Which device is better suited for high-speed wideband digitization?
The ADS5400IPZP is the appropriate choice for high-speed wideband digitization because its 1-GSPS sampling rate supports capture of much wider signal bandwidths than the 65-MSPS ADS5413IPHP. The ADS5413IPHP is better matched to lower-speed, lower-power acquisition channels.
Are both parts available in HTQFP packages from Texas Instruments?
Yes. Both are Texas Instruments devices in HTQFP packages: the ADS5400IPZP in a 100-pin HTQFP (PZP) and the ADS5413IPHP in a 48-pin HTQFP (PHP). The differing pin counts mean the packages are not interchangeable on the same PCB footprint.
