Product details
Overview
ADS62P15IRGCT from Texas Instruments is a dual-channel, 11-bit analog-to-digital converter (ADC) with 125 MSPS maximum sample rate, parallel CMOS and DDR LVDS output interfaces, 67.1 dBFS SNR at 50 MHz input, and integrated digital processing block supporting offset correction, fine gain adjustment (0.05 dB steps), decimation by 2/4/8, and programmable 24-tap filters - deployed in wireless infrastructure baseband receivers.
For engineers reviewing the ADS62P15IRGCT datasheet, ADS62P15IRGCT pinout, ADS62P15IRGCT application, or ADS62P15IRGCT equivalent, key selection considerations include dual-channel timing matching (±50 ps aperture delay skew), LVDS/CMOS interface flexibility, on-chip reference vs. external reference support, and digital processing enablement for real-time signal conditioning without FPGA offload.
Technical Context
The ADS62P15IRGCT employs a pipelined ADC architecture with internal sample-and-hold and low-jitter clock buffer to achieve 84 dBc SFDR at 50 MHz input while maintaining 11-bit no-missing-codes linearity. Its digital processing block operates independently per channel and includes configurable decimation and filter paths.
It supports three configuration modes: parallel pin control only (via CTRL1–CTRL3, SEN, SCLK), serial register programming only (via SEN/SCLK/SDATA with RESET low), or hybrid mode where parallel pins set power states and serial registers configure digital functions - enabling flexible integration into deterministic or adaptive signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 11-bit with guaranteed no missing codes across –40°C to 85°C - ensures monotonicity in closed-loop control and measurement systems. |
| Max Sample Rate | 125 MSPS - supports Nyquist sampling of IF signals up to 62.5 MHz in direct-conversion receivers. |
| SNR @ 50 MHz | 67.1 dBFS - enables >10.5 ENOB for high-fidelity digitization of narrowband RF signals in SDR and radar front ends. |
| SFDR @ 50 MHz | 84 dBc - suppresses spurious tones critical for adjacent-channel rejection in LTE/WiMAX base stations. |
| Digital Processing | Per-channel offset correction, fine gain (0.05 dB steps), decimation by 2/4/8, and 24-tap LP/HP/BP filters - reduces post-ADC FPGA resource usage. |
| Output Interface | Configurable parallel CMOS or DDR LVDS - allows trade-off between board-level routing simplicity (CMOS) and noise immunity & density (LVDS). |
| Reference | Internal 1.5 V reference (±0.25% gain error) or external reference support - eliminates external ref ICs unless tighter accuracy required. |
| Package | 64-pin QFN (9 mm × 9 mm, RGC) with exposed thermal pad - supports thermal dissipation up to 0.94 W (LVDS mode) on standard 4-layer PCB. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS62P25IRGCT | 12-bit resolution, same 125 MSPS rate, identical QFN-64 package and pinout - higher resolution but 0.3 dB lower SNR (66.8 dBFS) at 50 MHz. | Better suited for applications requiring finer amplitude quantization (e.g., high-precision test instrumentation), less ideal where SFDR dominates (e.g., wideband comms). | Select ADS62P25IRGCT when ENOB >10.8 is mandatory and SFDR ≥82 dBc suffices; verify layout compatibility via identical RGC footprint. |
| ADS62P45IRGCT | 14-bit resolution, 125 MSPS, same package - delivers 73.2 dBFS SNR and 92 dBc SFDR at 50 MHz, but consumes ~30% more power (1.225 W CMOS). | Targeted at ultra-high-fidelity applications like medical ultrasound beamforming where dynamic range exceeds 80 dB is essential. | Choose ADS62P45IRGCT only when system SNR/SFDR requirements exceed ADS62P15IRGCT capability and thermal/power budget permits. |
Compared with ADS62P15IRGCT, ADS62P25IRGCT trades 1-bit resolution for marginally lower power and unchanged pin compatibility, while ADS62P45IRGCT provides 3-bit resolution uplift at significantly higher power and cost - making ADS62P15IRGCT the optimal balance for cost-sensitive, high-SFDR wireless infrastructure designs.

FAQ
What is the maximum sample rate supported by the ADS62P15IRGCT?
The ADS62P15IRGCT supports a maximum sample rate of 125 MSPS across its full operating temperature range (–40°C to 85°C). This rate is validated with internal reference, 50% clock duty cycle, and –1 dBFS differential analog input. Performance metrics such as SNR and SFDR are specified at this rate, and the device maintains timing specifications (e.g., aperture jitter ≤130 fs rms) without derating.
Does the ADS62P15IRGCT require an external reference voltage?
No, the ADS62P15IRGCT includes an internal 1.5 V reference and operates fully functional without external reference components. However, it also supports external reference mode via the CM pin, allowing users to substitute a higher-accuracy or temperature-stable reference when system-level gain error budgets demand <±0.25% total error.
Can the ADS62P15IRGCT operate in both CMOS and LVDS output modes simultaneously?
No, the ADS62P15IRGCT supports either parallel CMOS or DDR LVDS output mode - not both simultaneously. The interface is selected at power-up via analog voltage levels on the SEN pin (per Table 5 in the datasheet), and the output drivers are hardwired to one physical interface path. Mode switching requires reset or reconfiguration.
What digital processing functions are available in the ADS62P15IRGCT's on-chip block?
ADS62P15IRGCT includes a configurable digital processing block with per-channel offset correction, fine gain adjustment (0.05 dB steps, 0–6 dB range), decimation by factors of 2/4/8, and programmable 24-tap FIR filters (low-pass, high-pass, band-pass). These functions are disabled by default and enabled via serial register writes or parallel pin settings.
Is the ADS62P15IRGCT pin-compatible with other devices in the ADS62Pxx family?
Yes, the ADS62P15IRGCT is pin-compatible with ADS62P2X (12-bit) and ADS62P4X (14-bit) variants in the same QFN-64 (RGC) package. All share identical pin assignments, power sequencing, and interface signaling - enabling resolution-scaling upgrades without PCB redesign, provided thermal and power delivery margins accommodate higher-resolution variants.
