Product details
Overview
ADS62P43IRGCT from Texas Instruments is a dual-channel, 14-bit analog-to-digital converter with 80 MSPS maximum sampling rate, DDR LVDS or parallel CMOS outputs, internal reference, and integrated digital processing block (offset correction, fine gain, decimation, 24-tap filters). It delivers 74.6 dBFS SINAD and 93 dBc SFDR at 10 MHz input, targeting high-fidelity signal acquisition in radar front-ends.
For engineers reviewing the ADS62P43IRGCT datasheet, ADS62P43IRGCT pinout, ADS62P43IRGCT application, or ADS62P43IRGCT equivalent, key selection criteria include its 80 MSPS sample rate, 14-bit no-missing-codes resolution, QFN-64 package thermal performance (θJA = 23.17 °C/W), and support for both internal/external reference modes with programmable coarse/fine gain.
Technical Context
The ADS62P43IRGCT implements a dual-sampling architecture with independent analog front-ends per channel, each featuring a low-jitter sample-and-hold and configurable input common-mode voltage (1.5 V ±0.1 V). Its digital processing block operates independently per channel and supports real-time offset correction, 0.05 dB-step fine gain adjustment, and decimation by 2/4/8.
Output interface flexibility includes DDR LVDS (with programmable drive strength and internal 100-Ω termination) or parallel CMOS (1.8–3.6 V DRVDD), both synchronized to an output clock (CLKOUT) with 3.5–7.5 ns propagation delay. Clock inputs accept sine, LVPECL, LVDS, or LVCMOS signals down to 400 mVPP differential amplitude.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes - guarantees monotonicity and full code coverage across temperature (–40°C to 85°C). |
| Max Sample Rate | 80 MSPS - enables Nyquist-limited baseband capture up to 40 MHz or undersampled IF digitization in SDR and radar. |
| SINAD @ 10 MHz | 74.6 dBFS - defines effective dynamic range for high-SNR applications like medical imaging and PA linearization. |
| SFDR @ 10 MHz | 93 dBc - determines spurious-free bandwidth for multi-tone RF systems such as 802.16d/e infrastructure. |
| Analog Power | 594 mW - measured at AVDD = 3.3 V, FS = 80 MSPS, enabling thermal design with θJA = 23.17 °C/W on standard PCBs. |
| Digital Interface | DDR LVDS or parallel CMOS - supports high-speed data transfer with low EMI (LVDS) or direct FPGA connection (CMOS). |
| Input Bandwidth | 450 MHz - allows wideband analog input without external anti-aliasing filter roll-off degradation. |
Pinout & Package
ADS62P43IRGCT is housed in a thermally enhanced 64-pin QFN package (9 mm × 9 mm, RGC designation) with exposed thermal pad. The package supports JEDEC-standard PCB layout for optimal thermal dissipation (θJC = 22.1 °C/W with 2 oz copper).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA_P / INA_M | Differential analog input, Channel A | Accepts 2 VPP differential signal with 1.5 V common-mode; high-impedance (>1 MΩ) input simplifies driver stage design. |
| INB_P / INB_M | Differential analog input, Channel B | Independent of Channel A; supports time-aligned dual-channel acquisition for I/Q or beamforming systems. |
| CLKP / CLKM | Differential clock input | Supports 400 mVPP–1.5 VPP sine/LVPECL/LVDS/LVCMOS; internal duty cycle stabilizer relaxes clock source requirements. |
| VCM | Common-mode reference | 1.5 V output when using internal reference; used to bias external ADC drivers or terminate analog inputs. |
| DA0–DA13 / DB0–DB13 | Parallel CMOS data outputs | 14-bit straight binary or 2's complement format; multiplexed mode available for reduced pin count in resource-constrained FPGAs. |
| CLKOUTP / CLKOUTM | DDR LVDS output clock | Source-synchronous clock for LVDS data capture; 46–53% duty cycle ensures robust setup/hold timing margins. |
| CTRL1–CTRL3 | Parallel configuration control | Set power-down, standby, or MUX mode at power-up without serial programming; eliminates boot firmware dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel 14-bit ADC with 80 MSPS | Enables simultaneous high-resolution sampling for I/Q demodulation or phased-array radar channel pairs without interleaving artifacts. |
| Programmable digital processing block | On-chip offset correction, 0.05 dB-step fine gain, decimation (2/4/8), and 24-tap FIR filters reduce FPGA logic utilization and latency in real-time signal chains. |
| Internal 1.5 V reference with external option | Eliminates external reference IC and decoupling capacitors; external reference mode supports precision calibration or system-level voltage alignment. |
| DDR LVDS + parallel CMOS dual interface | Provides migration path from legacy CMOS designs to high-speed LVDS while maintaining pin compatibility across ADS62P4X family variants. |
| 64-QFN package with thermal pad | Delivers 22.1 °C/W junction-to-case thermal resistance when soldered to 4-layer JEDEC board - critical for sustained 80 MSPS operation in enclosed industrial enclosures. |

FAQ
What is the maximum sampling rate supported by ADS62P43IRGCT?
The ADS62P43IRGCT supports a maximum sampling rate of 80 MSPS, as specified in the SLAS561C datasheet. This rate is validated across the full industrial temperature range (–40°C to 85°C) with AVDD = 3.3 V and proper clock conditioning. Exceeding this rate may result in degraded AC performance including reduced SFDR and increased aperture jitter.
Does ADS62P43IRGCT require an external reference voltage?
No, ADS62P43IRGCT includes an internal 1.5 V reference and operates fully functional without external reference components. However, it also supports external reference mode via the VCM pin (1.45–1.55 V range), enabling system-level calibration or synchronization with other precision converters in the same signal chain.
What output interfaces does ADS62P43IRGCT support?
ADS62P43IRGCT supports two mutually exclusive output interfaces: DDR LVDS (differential, 3.3 V DRVDD, 100 Ω termination) and parallel CMOS (1.8–3.6 V DRVDD, configurable drive strength). Interface selection is determined at power-up via SEN pin voltage level and cannot be changed dynamically during operation.
How is channel synchronization handled in ADS62P43IRGCT?
ADS62P43IRGCT achieves tight channel-to-channel synchronization with ≤50 ps aperture delay matching within the same device, verified across temperature. This is enabled by shared clock distribution, matched analog front-end paths, and simultaneous sampling architecture-critical for I/Q imbalance correction and beamforming accuracy.
Can the digital processing block in ADS62P43IRGCT be bypassed?
Yes, the digital processing block (offset correction, fine gain, decimation, FIR filters) is disabled by default at power-up. It can be selectively enabled via serial interface register writes or parallel pin configuration (CTRL1–CTRL3), allowing full analog-path transparency when lowest latency and deterministic timing are required.
