Product details
Overview
ADS62C15IRGC25 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, internal reference, and SNRBoost technology enabling 77.5 dBFS SNR at 20 MHz bandwidth. It operates across –40°C to 85°C and targets high-performance RF sampling in wireless infrastructure.
For engineers reviewing the ADS62C15IRGC25 datasheet, ADS62C15IRGC25 pinout, ADS62C15IRGC25 application, or ADS62C15IRGC25 equivalent, key selection considerations include dual-channel 11-bit resolution at 125 MSPS, programmable coarse/fine gain for SNR/SFDR trade-offs, clock duty cycle stabilization, and support for both internal/external reference configurations.
Technical Context
The ADS62C15IRGC25 integrates two independent 11-bit ADC cores sharing a low-jitter clock buffer and analog front-end, each with dedicated digital processing blocks featuring offset correction, 0.05 dB fine gain adjustment, decimation by 2/4/8, and 24-tap programmable filters. Its SNRBoost technology improves quantization-limited SNR for sub-Nyquist bandwidths.
It supports flexible interface configuration via parallel control pins (SEN, SCLK, CTRL1–3) or serial SPI-like programming (SEN/SCLK/SDATA), with configurable power-down modes per channel and MUX mode for CMOS output. Clock input accepts sine, LVPECL, LVDS, or LVCMOS with amplitude down to 400 mVPP and duty cycle stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 11-bit - guarantees no missing codes and deterministic quantization step size for precise signal reconstruction. |
| Max Sample Rate | 125 MSPS - enables Nyquist-limited baseband capture up to 62.5 MHz or IF sampling of multi-carrier LTE/WiMAX signals. |
| SFDR @ 117 MHz | 82 dBc - ensures clean spectral representation for demanding adjacent-channel rejection in PA linearization. |
| SNR @ 117 MHz | 67 dBFS - provides >10-bit effective resolution for high-fidelity digitization of wideband RF inputs. |

Pinout & Package
ADS62C15IRGC25 is housed in a 64-pin QFN package (RGC) with exposed thermal pad. Pin functions are defined per TI SLAS577E Rev F (Feb 2012), supporting dual analog inputs (INA_P/M, INB_P/M), differential clock (CLKP/CLKM), CMOS/LVDS outputs (DA0–DA10, DB0–DB10, CLKOUTP/M), serial control (SEN, SCLK, SDATA, SDOUT), and power domains (AVDD, DRVDD, AGND, DRGND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA_P / INA_M | Differential analog input, Channel A | Accepts 2 VPP full-scale differential signal; common-mode voltage fixed at 1.5 V in internal reference mode. |
| INB_P / INB_M | Differential analog input, Channel B | Independent path with identical specs; 92 dB crosstalk ensures isolation from Channel A. |
| CLKP / CLKM | Differential clock input | Supports 400 mVPP min amplitude; integrated duty cycle stabilizer relaxes clock source requirements. |
| DA0–DA10 / DB0–DB10 | Parallel CMOS data outputs | 11-bit wide per channel; configurable for straight binary or 2's complement format via SEN pin. |
| CLKOUTP / CLKOUTM | DDR LVDS output clock | Provides source-synchronous timing for DDR LVDS data; 46–52% duty cycle tolerance. |
| SEN / SCLK / SDATA | Serial interface control | Enable SPI-like register access; required for configuring digital processing block and power modes. |
| CTRL1–CTRL3 | Parallel digital control | Select channel standby, output disable, or full power-down without serial interface involvement. |
Key Features
| Feature | Design Value |
|---|---|
| Clock Duty Cycle Stabilizer | Compensates for input clock asymmetry to maintain aperture jitter ≤130 fs rms, critical for SFDR stability. |
| SNRBoost Technology | Delivers +4.5 dB SNR gain at 20 MHz bandwidth-verified at 125 MSPS-without increasing power or latency. |
| Programmable Fine Gain | 0.05 dB steps across 0–6 dB range enable precise optimization of SFDR vs. SNR for specific input signal levels. |
| Dual Digital Processing Blocks | Per-channel 24-tap FIR filters (LP/HP/BP), decimation, and offset correction reduce FPGA/DSP preprocessing load. |
| Flexible Reference Options | Internal reference eliminates external components; external reference mode supports precision system-level calibration. |
Applications
| Wireless Base Station Receiver | Software Defined Radio (SDR) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 11-bit, 125+ MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS62P15IRGC25 | 12-bit resolution, same 125 MSPS rate, identical package and pinout; higher SNR (72 dBFS) but no SNRBoost. | Better DC accuracy and SFDR for test equipment; lacks bandwidth-optimized SNR enhancement for narrowband radar. | Choose when absolute linearity and harmonic suppression outweigh adaptive SNR gain. |
| AD9233BCPZ-125 | Analog Devices part: 12-bit, 125 MSPS, serial LVDS output only; no parallel CMOS option or on-chip digital processing block. | Requires external FPGA for filtering/decimation; simpler interface but higher system-level design effort. | Prefer when board space allows FPGA integration and LVDS-only interface suffices. |
Compared with ADS62C15IRGC25, ADS62P15IRGC25 offers higher resolution without SNRBoost, while AD9233BCPZ-125 trades integrated digital features for pure analog performance and serial-only output-making ADS62C15IRGC25 optimal for embedded signal processing where on-chip decimation and programmable gain reduce host processor load.

FAQ
What is the maximum sampling rate supported by the ADS62C15IRGC25?
The ADS62C15IRGC25 supports a maximum sampling rate of 125 MSPS, validated across the full industrial temperature range (–40°C to 85°C) with AVDD = 3.3 V and proper clock conditioning. This rate enables Nyquist-zone digitization up to 62.5 MHz and is specified with 50% clock duty cycle and –1 dBFS input signal per TI SLAS577E.
Does the ADS62C15IRGC25 support both CMOS and LVDS output interfaces simultaneously?
No, the ADS62C15IRGC25 supports either parallel CMOS or DDR LVDS output mode-not both concurrently. Interface selection is determined at power-up via the SEN pin voltage level (per Table 5 in SLAS577E); changing modes requires reset and reconfiguration.
How does SNRBoost technology improve performance in the ADS62C15IRGC25?
SNRBoost in the ADS62C15IRGC25 delivers up to +4.5 dB SNR improvement for bandwidths less than Nyquist (e.g., 77.5 dBFS at 20 MHz BW vs. 73 dBFS without), achieved through proprietary digital noise-shaping within the on-chip processing block-verified at 125 MSPS with internal reference enabled.
What are the power supply requirements for the ADS62C15IRGC25?
The ADS62C15IRGC25 requires AVDD = 3.0–3.6 V (typ. 3.3 V) for analog circuitry and DRVDD = 1.8–3.6 V (1.8 V for CMOS, 3.3 V for LVDS) for digital outputs. Total power is 0.74 W (CMOS, no load) or 0.94 W (LVDS), with global power-down reducing consumption to 30–60 mW.
Can the ADS62C15IRGC25 be configured using only hardware pins, without serial programming?
Yes, the ADS62C15IRGC25 supports full parallel interface configuration using SEN, SCLK, and CTRL1–CTRL3 pins-no serial interface required. For example, SCLK and SEN voltages set reference source and output format, while CTRL1–CTRL3 control channel power states per Table 6 in SLAS577E.
