Replacement verdict
Compatible functional replacement candidate
The ADS5400IPZP and ADS5400IPZPR are functionally identical 12-bit 1 GSPS analog-to-digital converters from Texas Instruments, differing only in packaging format (tube vs. tape-and-reel). The ADS5400IPZPR is a direct drop-in replacement for the ADS5400IPZP in both electrical performance and PCB footprint, making it suitable for high-volume automated assembly without any design modification.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5400IPZP | ADS5400IPZPR | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Determines the quantization precision of the ADC; identical resolution means equivalent signal-to-noise performance for a given input. |
| Sampling Rate | 1 GSPS | 1 GSPS | Sets the maximum input bandwidth the converter can capture; matching rates ensure the same Nyquist-limited bandwidth. |
| Number of Input Channels | 1 | 1 | Defines how many analog signals can be digitized simultaneously; both are single-channel devices. |
| Input Type | Differential | Differential | Differential inputs improve common-mode rejection and dynamic performance; identical input topology supports drop-in substitution. |
| Output Interface | LVDS (DDR) | LVDS (DDR) | Determines compatibility with the downstream FPGA/ASIC receiver; matching LVDS DDR output allows the same digital interface design. |
| Supply Voltage | 3.3 V (analog), 1.8 V (digital) | 3.3 V (analog), 1.8 V (digital) | Power rail requirements must match for the board to be reused without redesign of the power tree. |
| Package / Case | 100-TQFP (PZP) | 100-TQFP (PZP) | Footprint and thermal characteristics must match for physical board compatibility; identical package enables direct replacement. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the part meets the environmental requirements of the target application; matching ranges confirm equivalent operating envelopes. |
| Packaging / Reel Option | Tray | Tape & Reel | Affects manufacturing handling and pick-and-place assembly; the R suffix denotes reel packaging for high-volume automated production. |

Frequently asked questions
What is the difference between the ADS5400IPZP and the ADS5400IPZPR?
The ADS5400IPZP and ADS5400IPZPR are the same analog-to-digital converter device; the difference is packaging format. The ADS5400IPZP is supplied in a standard tray, while the ADS5400IPZPR is supplied in tape-and-reel packaging for automated assembly. Both use the same HTQFP-100 (PZP) package and share identical electrical specifications.
Are the ADS5400IPZP and ADS5400IPZPR electrically identical?
Yes. Both orderable part numbers refer to the same ADS5400 12-bit, 1-GSPS analog-to-digital converter die in the same 100-pin HTQFP package. Electrical parameters, pinout, and functional behavior are identical; only the shipping media differ.
What are the key performance specifications of the ADS5400?
The ADS5400 is a 12-bit ADC with a maximum sampling rate of 1 GSPS. It operates from a 5 V analog supply and a 3.3 V digital supply, and provides a parallel LVDS-compatible output interface. It is specified for operation over the industrial temperature range of -40°C to +85°C.
Can the ADS5400IPZP and ADS5400IPZPR be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because both are the same device in the same HTQFP-100 package. The choice between them depends only on the assembly process: tray (IPZP) for low-volume or manual handling, and tape-and-reel (IPZPR) for high-volume automated pick-and-place lines.
What package does the ADS5400IPZP use, and is it the same for the ADS5400IPZPR?
Both parts use the PZP suffix designating a 100-pin HTQFP (PowerPAD thermodynamically enhanced quad flat package). The package body, pin count, and thermal pad are identical for both orderable part numbers.
Which part number should be ordered for high-volume automated production?
The ADS5400IPZPR is the tape-and-reel variant, which is intended for automated surface-mount assembly lines. The ADS5400IPZP tray variant is typically used for prototyping, low-volume builds, or manual assembly.
Do both parts share the same operating temperature range and supply requirements?
Yes. Because they are the same device, both the ADS5400IPZP and ADS5400IPZPR are specified over the industrial temperature range of -40°C to +85°C and require the same 5 V analog and 3.3 V digital supplies.
