Product details
Overview
ADS5282IRGCT from Texas Instruments is a 12-bit, 65MSPS octal-channel analog-to-digital converter with serialized LVDS outputs, integrated PLL clock buffer, programmable digital gain (0–12 dB), and internal/external reference selection. It operates on 3.3V analog and 1.8V digital supplies, delivers 70dBFS SNR at 10MHz IF, and targets high-density data acquisition in medical imaging and wireless infrastructure.
For engineers reviewing the ADS5282IRGCT datasheet, ADS5282IRGCT pinout, ADS5282IRGCT application, or ADS5282IRGCT equivalent, this page provides verified specifications, QFN-64 package layout, real-world use scenarios, and two confirmed alternative parts - all grounded in TI's SBAS397I datasheet (Rev. June 2012) and official ordering information.
Technical Context
The ADS5282IRGCT implements an 8-channel pipeline ADC architecture with per-channel digital gain control, low-frequency noise suppression mode, and 6dB overload recovery in one clock cycle. Its serialized DDR LVDS interface uses dual clocks: ADCLKP/ADCLKN (1× sample rate, up to 65 MHz) and LCLKP/LCLKN (6× sample rate, up to 390 MHz).
It supports both differential and single-ended clock inputs with duty-cycle correction, offers straight offset binary or two's complement output format, and includes configurable power-down modes - complete (45 mW), partial (135 mW at 65 MSPS), and clock-gated (88 mW) - all validated across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution & Speed | 12-bit resolution at 65 MSPS sampling rate - enables high-fidelity digitization of wideband IF signals up to 520 MHz analog input bandwidth. |
| Analog Input Range | 2 VPP differential full-scale range - compatible with standard RF transformer-coupled front-ends without external scaling. |
| Dynamic Performance | 70 dBFS SNR at 10 MHz IF, –92 dBFS third-order IMD - meets demanding spurious-free requirements in base-station receivers. |
| Power Dissipation | 639–744.6 mW total (AVDD + LVDD) at 65 MSPS - optimized for multi-channel systems where per-channel efficiency matters. |
| Digital Interface | Serialized DDR LVDS outputs with 6× bit clock (LCLKP/LCLKN) and 1× frame clock (ADCLKP/ADCLKN) - reduces PCB routing complexity vs. parallel interfaces. |
| Reference Options | Internal trimmed 2.0 V reference (±15 ppm/°C TC) or external 2.5 V/0.5 V reference pair - supports precision calibration or system-level reference sharing. |
| Supply Voltages | 3.3 V analog (AVDD), 1.8 V digital (LVDD) - separates noise-sensitive analog domain from switching digital I/O, easing power integrity design. |
Pinout & Package
ADS5282IRGCT is housed in a thermally enhanced 64-pin QFN package (9 mm × 9 mm, RGC suffix) with exposed PowerPAD™ thermal pad. Pin assignments are defined per TI's SBAS397I datasheet, Table 3 (QFN-64). The package supports industrial temperature operation (–40°C to +85°C) and RoHS-compliant assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1P–IN8P / IN1N–IN8N | Differential analog inputs (8 channels) | Accepts 2 VPP differential signals; each pair requires matched trace lengths and 100 Ω termination at receiver. |
| ADCLKP / ADCLKN | LVDS frame clock output (1× sample rate) | Provides synchronized timing reference for FPGA capture logic; frequency = sampling rate (up to 65 MHz). |
| LCLKP / LCLKN | LVDS bit clock output (6× sample rate) | Drives DDR serialization clock; frequency = 6 × sampling rate (up to 390 MHz); critical for setup/hold margin. |
| OUT1P–OUT8P / OUT1N–OUT8N | LVDS serialized data outputs (8 channels) | Each channel outputs 12-bit DDR data on rising/falling edges of LCLK; requires 100 Ω differential termination. |
| CLKP / CLKN | Differential clock input | Accepts LVDS/LVPECL/CMOS clocks; internal DCC corrects duty cycle to maintain >45%–55% across process/temperature. |
| INT/EXT | Reference mode select | High = internal reference enabled; low = external REFT/REFB used - sets bias and common-mode voltage source. |
| PD / RESET | Power-down and hardware reset | PD asserts low-power state; RESET initializes registers and clears internal state - both active-low, CMOS-compatible. |
| VCM | Common-mode output | Supplies stable 1.5 V reference for AC-coupled input stages; sourced/sunk ±2 mA - eliminates need for external bias network. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable digital gain (0–12 dB) | Adjusts full-scale code mapping digitally - avoids analog gain stages and preserves SNR while adapting to varying signal levels. |
| Low-frequency noise suppression mode | Reduces 1/f noise contribution in baseband applications - improves effective resolution for DC-coupled sensor interfaces. |
| 6dB overload recovery in one clock cycle | Restores valid conversion within a single sample period after clipping - prevents extended data corruption in burst-mode RF systems. |
| Internal 2.0 V reference (±15 ppm/°C) | Eliminates external reference IC and associated layout sensitivity - simplifies BOM and improves long-term drift performance. |
| Configurable LVDS drive current | Supports 3.5 mA default or user-adjusted current via ISET resistor (56.2 kΩ) - optimizes signal integrity across varied trace lengths and loads. |
Applications
| Ultrasound Beamforming | 4G/5G Massive MIMO Receivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS5281IRGCT | Same QFN-64 package and feature set, but rated for 50 MSPS max (vs. 65 MSPS); 10–15% lower power at equivalent rates. | Valid for cost-sensitive 50 MSPS systems where SNR >70 dBFS at 10 MHz IF remains sufficient. | Select when sampling rate headroom is not required and board layout must remain identical. |
| ADS5272IRGCT | Same 65 MSPS speed and QFN-64 footprint, but lacks internal PLL clock buffer and has fixed 2.0 V reference only. | Suitable for systems with external clock synthesis and no need for on-chip clock conditioning or reference flexibility. | Choose when clock tree is already centralized and reference sourcing is handled externally - reduces component count. |
Compared with ADS5281IRGCT and ADS5272IRGCT, the ADS5282IRGCT uniquely combines 65 MSPS speed, integrated PLL clock buffer, and dual-reference support - making it optimal for space-constrained, high-SNR systems requiring minimal external timing components.

FAQ
What is the maximum sampling rate supported by the ADS5282IRGCT?
The ADS5282IRGCT supports a maximum sampling rate of 65 MSPS, as specified in TI's SBAS397I datasheet (Rev. June 2012). This rating applies across the full industrial temperature range (–40°C to +85°C) with AVDD = 3.3 V and LVDD = 1.8 V. At this rate, the device delivers 70 dBFS SNR at 10 MHz IF and maintains <±0.9 LSB DNL. The ADS5282IRGCT is the highest-speed variant in the ADS528x family.
Does the ADS5282IRGCT require an external clock source, or does it include a PLL?
The ADS5282IRGCT includes an integrated PLL-based clock buffer that accepts a single-ended or differential input clock (CLKP/CLKN) and generates clean, low-jitter ADCLKP/ADCLKN (1×) and LCLKP/LCLKN (6×) outputs. While it does not generate clocks autonomously, the on-chip PLL eliminates need for external clock synthesizers in most applications - a key differentiator from ADS5272IRGCT, which lacks this function.
What package type is used for the ADS5282IRGCT, and is thermal management supported?
The ADS5282IRGCT uses a 64-pin QFN package (9 mm × 9 mm, RGC suffix) with an exposed PowerPAD™ thermal pad. This construction enables efficient heat dissipation - critical given its 639–744.6 mW total power consumption at 65 MSPS. TI recommends soldering the PowerPAD to a large copper pour connected to internal ground planes for optimal thermal performance in continuous operation.
Can the ADS5282IRGCT operate with only an external reference, and what are the voltage requirements?
Yes, the ADS5282IRGCT supports external reference mode via the INT/EXT pin. When pulled low, it uses REFT (2.4–2.6 V) and REFB (0.4–0.6 V) pins to accept an external reference pair, delivering a 2.0 V nominal reference span. The device draws up to 3.5 mA from these pins in external mode - a value explicitly characterized in the datasheet's "External Reference Loading" table for ADS5282.
How many LVDS data lanes does the ADS5282IRGCT provide, and what is the serialization scheme?
The ADS5282IRGCT provides eight independent LVDS data lanes (OUT1P/OUT1N through OUT8P/OUT8N), each carrying serialized 12-bit DDR data aligned to the 6× LCLK. Each lane outputs two 12-bit words per LCLK cycle - one on the rising edge and one on the falling edge - achieving effective throughput of 1560 Mbps per channel at 65 MSPS. No multiplexing across lanes occurs; each corresponds to one physical ADC channel.
