Replacement verdict
Not a drop-in replacement
The ADS54J60IRMP and ADS5481IRGCT are not drop-in replacements for one another. They differ in resolution, sampling rate, output interface, and package footprint, so a direct board-level substitution is not feasible without redesign of the signal chain, clocking, and layout.

Key electrical and mechanical differences between the two devices
| Parameter | ADS54J60IRMP | ADS5481IRGCT | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Both are 16-bit ADCs, so quantization noise floor and dynamic range class are comparable. |
| Sampling Rate | 1 GSPS | 80 MSPS | Sample rate determines the maximum input bandwidth and Nyquist zone; a 1 GSPS device supports far wider signal bandwidth than an 80 MSPS device. |
| Output Interface | JESD204B serial lanes | Parallel LVDS | The digital output format dictates the FPGA/ASIC interface, lane count, and board routing; these are not pin- or protocol-compatible. |
| Input Type | Differential | Differential | Both accept differential analog inputs, allowing similar front-end transformer or amplifier coupling. |
| Supply Voltage | 1.9 V (analog), 1.2 V (digital) | 3.3 V (analog), 3.3 V (digital) | Different supply rails require different power sequencing and regulators; the two parts cannot share the same power tree. |
| Package | 72-pin VQFN | 64-pin VQFN | Package footprint and pin count differ, so the parts are not drop-in board replacements. |
| Power Consumption | Approximately 1.4 W | Approximately 1.4 W | Similar power draw affects thermal design and supply sizing; comparable dissipation simplifies thermal budgeting. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical industrial temperature ratings mean both suit the same environmental conditions. |

Frequently asked questions
What are the primary differences between the ADS54J60IRMP and ADS5481IRGCT?
The ADS54J60IRMP is a dual-channel, 16-bit, 1-GSPS analog-to-digital converter with a JESD204B serial interface, while the ADS5481IRGCT is a single-channel, 16-bit, 80-MSPS ADC with a parallel LVDS CMOS output interface. They differ in channel count, maximum sample rate, output interface, and package.
What are the maximum sample rates of the ADS54J60IRMP and ADS5481IRGCT?
The ADS54J60IRMP supports a maximum sample rate of 1 GSPS per channel. The ADS5481IRGCT supports a maximum sample rate of 80 MSPS.
What output interfaces do the ADS54J60IRMP and ADS5481IRGCT use?
The ADS54J60IRMP uses a JESD204B serial output interface. The ADS5481IRGCT uses a parallel LVDS output interface.
How many ADC channels does each device provide?
The ADS54J60IRMP is a dual-channel ADC, providing two simultaneous conversion channels. The ADS5481IRGCT is a single-channel ADC.
What resolution do the ADS54J60IRMP and ADS5481IRGCT provide?
Both devices provide 16-bit resolution.
In what packages are the ADS54J60IRMP and ADS5481IRGCT supplied?
The ADS54J60IRMP is supplied in a 72-pin VQFN package. The ADS5481IRGCT is supplied in a 64-pin VQFN package.
Can the ADS54J60IRMP and ADS5481IRGCT be used interchangeably in the same design?
No. The two devices differ in channel count, sample rate, output interface, pinout, and package, so they are not pin-compatible or functionally interchangeable without a complete redesign of the interface and PCB layout.
