Replacement verdict
Compatible functional replacement candidate
The ADS5287IRGCR is a viable functional replacement candidate for the ADS5263IRGCT in applications where the higher sample rate and reduced channel count are acceptable. Both devices share the same 64-pin VQFN package, 14-bit resolution, and serial LVDS interface, but the ADS5263IRGCT offers four channels at 125 MSPS while the ADS5287IRGCR provides eight channels at 65 MSPS. Designers must validate channel count requirements, sampling rate headroom, and power budget before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5263IRGCT | ADS5287IRGCR | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 10 bit | Resolution determines the dynamic range and SNR ceiling; a 16-bit ADC offers far finer quantization than a 10-bit device, so these are not functionally interchangeable in precision applications. |
| Number of Channels | 4 | 8 | Channel count dictates how many signal inputs can be sampled simultaneously; the 8-channel device suits multi-channel arrays while the 4-channel part fits lower-channel-count systems. |
| Maximum Sample Rate | 100 MSPS | 65 MSPS | Sample rate sets the maximum signal bandwidth that can be captured; the higher-rate device supports wider-bandwidth inputs. |
| Interface Type | Serial LVDS | Serial LVDS | The digital output interface must match the receiving FPGA/ASIC; both use serial LVDS, easing board-level compatibility. |
| Supply Voltage | 1.8 V (analog and digital) | 1.8 V (analog and digital) | Supply voltage must match the board power rails; identical 1.8 V operation simplifies power design reuse. |
| Package | 64-VQFN (9x9 mm) | 64-VQFN (9x9 mm) | Package footprint and pinout determine PCB layout compatibility; matching VQFN packages allow potential board reuse. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The temperature range must cover the application environment; identical industrial ranges suit the same operating conditions. |
| Power Consumption (per channel) | Approx. 155 mW/channel | Approx. 64 mW/channel | Power per channel affects thermal budget and supply sizing; the higher-resolution device consumes substantially more power per channel. |

Frequently asked questions
What are the key differences between the ADS5263IRGCT and ADS5287IRGCR?
The ADS5263IRGCT is a 16-bit, 100-MSPS quad-channel ADC with a serial LVDS interface, while the ADS5287IRGCR is a 12-bit, 65-MSPS octal-channel ADC with a serial LVDS interface. The ADS5263 offers higher resolution and sample rate per channel with four channels, whereas the ADS5287 provides twice the channel count at lower resolution and sample rate.
Are the ADS5263IRGCT and ADS5287IRGCR pin-compatible?
No. The ADS5263IRGCT is supplied in a 64-pin VQFN (RGC) package with four analog input channels, and the ADS5287IRGCR is supplied in a 64-pin VQFN (RGC) package with eight analog input channels. Although both use the RGC package outline, the pin functions and channel assignments differ, so they are not drop-in replacements.
What are the resolution and sampling rate specifications of each device?
The ADS5263IRGCT provides 16-bit resolution at a maximum sample rate of 100 MSPS. The ADS5287IRGCR provides 12-bit resolution at a maximum sample rate of 65 MSPS.
How many analog input channels does each ADC provide?
The ADS5263IRGCT integrates four analog-to-digital converter channels. The ADS5287IRGCR integrates eight analog-to-digital converter channels.
What digital output interface do these ADCs use?
Both devices use a serialized LVDS output interface. The ADS5263IRGCT provides serial LVDS outputs for its four channels, and the ADS5287IRGCR provides serial LVDS outputs for its eight channels, allowing high-speed digital data transfer to an FPGA or DSP.
What are the typical applications for each device?
The ADS5263IRGCT is suited to high-resolution, high-speed acquisition such as medical imaging, test and measurement, and radar where four 16-bit channels at up to 100 MSPS are required. The ADS5287IRGCR is suited to multi-channel, high-speed acquisition such as ultrasound and multi-channel instrumentation where eight 12-bit channels at up to 65 MSPS are needed.
Can the ADS5263IRGCT and ADS5287IRGCR be used interchangeably in an existing design?
No. Because the devices differ in resolution, channel count, sample rate, and pin functions, they cannot be used interchangeably without redesigning the analog front end, clocking, digital interface, and PCB layout, and revalidating performance against the system requirements.
