Product details
Overview
ADC08DL500CIVV/NOPB from Texas Instruments is a dual-channel, 8-bit, 500 MSPS analog-to-digital converter optimized for direct RF sampling and high-speed communications systems. It operates from a single +1.9 V supply, delivers 7.2 ENOB at 125 MHz input, achieves 10⁻¹⁸ code error rate, and consumes 1.25 W in 1:2 demux mode - enabling satellite modems and digital oscilloscopes requiring wideband digitization with low power.
For engineers reviewing the ADC08DL500CIVV/NOPB datasheet, ADC08DL500CIVV/NOPB pinout, ADC08DL500CIVV/NOPB application, or ADC08DL500CIVV/NOPB equivalent, this page provides verified technical context, validated LVDS output timing, confirmed dual-ADC channel synchronization behavior, calibrated full-scale range control via FSR/ALT_ECE, and precise thermal and supply decoupling requirements per TI SNAS495C.
Technical Context
The ADC08DL500CIVV/NOPB integrates two independent 8-bit ADC cores sharing a common 500 MHz sampling clock, each with fully differential comparator architecture and folding-interpolating conversion. Its internal sample-and-hold amplifier supports direct RF down-conversion up to 2 GHz full-power bandwidth and maintains flat gain response (±0.8 dBFS) to 248 MHz.
It implements duty-cycle-corrected sampling clock generation, selectable 1:2 demultiplexed LVDS data outputs (DQ/DId pairs), and configurable extended control mode via serial interface. Calibration logic enables no-missing-codes operation across −40°C to +70°C and supports programmable full-scale voltage adjustment through register or pin control.
Key Specifications

|---|---|
| Resolution | 8 bits with guaranteed no missing codes over full temperature range |
| Max Conversion Rate | 500 MSPS per channel, supporting simultaneous dual-channel sampling |

| DNL | ±0.15 LSB typical - critical for monotonicity in closed-loop control and radar pulse detection |
Pinout & Package
The ADC08DL500CIVV/NOPB is housed in a lead-free 144-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Power and ground pins are distributed across multiple corners to minimize supply noise coupling between analog and digital domains.

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 |
|---|---|---|---|
| ADS52J90IRGCT | 10-bit, 1 GSPS dual ADC; higher resolution but 2.5× higher power (3.1 W); JESD204B output instead of LVDS | Targets 5G NR baseband where quantization noise dominates; not drop-in due to interface and supply differences | Select when >8-bit ENOB and JESD204B FPGA compatibility are required; verify layout changes for 1.8 V/1.0 V dual supplies |
| AD9286BCPZ-500 | 8-bit, 500 MSPS dual ADC; identical resolution and rate, but uses CMOS outputs (not LVDS); 1.8 V supply only | Preferred for lower-cost FPGA interfaces without LVDS receivers; lacks duty-cycle correction and extended control mode | Choose for cost-sensitive test gear where LVDS noise immunity is non-critical and board space allows wider CMOS trace routing |
Compared with ADS52J90IRGCT and AD9286BCPZ-500, the ADC08DL500CIVV/NOPB uniquely balances 500 MSPS dual-channel sampling, LVDS noise resilience, sub-watt-per-channel power, and pin-configurable full-scale range - making it optimal for compact, thermally constrained RF instrumentation where deterministic timing and low C.E.R. are mandatory.

FAQ
What is the operating temperature range for the ADC08DL500CIVV/NOPB?
The ADC08DL500CIVV/NOPB is specified for operation across −40°C to +70°C (modified industrial range). This range is validated for all key parameters including ENOB, SINAD, and code error rate, and applies to both normal and extended control modes. The device guarantees no missing codes across this full range, as confirmed in TI SNAS495C Section 6.1.
Does the ADC08DL500CIVV/NOPB support DC-coupled analog inputs?
Yes, the ADC08DL500CIVV/NOPB supports DC-coupled analog inputs. When used in DC-coupling mode, the VCMO pin must be driven to the required common-mode voltage (0.9 V to 1.6 V), and VINI+/VINI− and VINQ+/VINQ− must remain within 0 V to 2.15 V (100% duty cycle) per the Operating Ratings table. AC coupling remains the default configuration for RF applications.
How does the 1:2 demultiplexing affect the output data rate of the ADC08DL500CIVV/NOPB?
In 1:2 demux mode, the ADC08DL500CIVV/NOPB outputs two time-interleaved data streams per channel - DQ (non-delayed) and DId (one-clock-cycle delayed). At 500 MSPS sampling, each LVDS pair runs at 250 MHz in SDR mode or 125 MHz in DDR mode. This reduces FPGA interface speed requirements while preserving full Nyquist bandwidth.
Can the ADC08DL500CIVV/NOPB be synchronized across multiple devices?
Yes, the ADC08DL500CIVV/NOPB supports multi-device synchronization via its differential DCLK_RST+ and DCLK_RST− pins (pins 17 and 16 when DRST_SEL = low). A synchronized reset pulse aligns internal sampling clocks and DCLK output phases across multiple converters, enabling coherent array processing in phased-array or MIMO systems.
What is the purpose of the CalRun pin on the ADC08DL500CIVV/NOPB?
The CalRun pin (pin 140) outputs a logic high signal during active on-chip calibration - such as power-up calibration or triggered recalibration via the CAL pin. This allows system firmware to pause data capture or delay register reads until calibration completes, ensuring consistent INL/DNL and offset performance. Its behavior is documented in TI SNAS495C Pin Functions table.
