Product details
Overview
ADC08D1520DEV/NOPB from Texas Instruments is a dual, low-power, 8-bit CMOS analog-to-digital converter with interleaved operation up to 1.5 GSPS per channel or single-channel 3.0 GSPS mode. It delivers 7.4 ENOB at 748 MHz input and 1.5 GHz sampling, features LVDS outputs compliant with IEEE 1596.3-1996, and operates from a single +1.9 V ±0.1 V supply. It is used in direct RF down-conversion systems requiring high dynamic range and precise timing alignment.
For engineers reviewing the ADC08D1520DEV/NOPB datasheet, ADC08D1520DEV/NOPB pinout, ADC08D1520DEV/NOPB application, or ADC08D1520DEV/NOPB equivalent, key selection criteria include guaranteed no-missing-codes performance over −40°C to +85°C, selectable 1:1 or 1:2 output demux, dual-channel synchronization capability, and support for both SDR and DDR LVDS clocking modes.
Technical Context
The ADC08D1520DEV/NOPB employs a folding-and-interpolating architecture with fully differential comparators and an innovative sample-and-hold amplifier design. Its self-calibration scheme ensures stable DNL (±0.15 LSB typ) and ENOB (7.4 bits typ @ 748 MHz) across temperature and process variation.
It supports interleave-mode operation for 3.0 GSPS aggregate throughput, multiple-ADC synchronization via DCLK_RST+/−, and flexible output formatting including offset binary coding and adjustable common-mode voltage (0.8–1.2 V). The device includes dedicated test pattern generation and duty-cycle-corrected sample clock functionality.
Key Specifications

Pinout & Package
ADC08D1520DEV/NOPB is housed in a thermally enhanced 128-pin HLQFP package with exposed thermal pad requiring soldering to ground plane per TI SNAS357D. Pin functions are validated per official TI pin description table (SNAS357D Rev. March 2013).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+/CLK− | Differential sampling clock input | AC-coupled inputs sampled on falling edge of CLK+; supports 1.5 GHz max input rate |
| VINI+/VINI−, VINQ+/VINQ− | Differential analog inputs (I/Q channels) | Programmable full-scale range (650–940 mVP-P) via FSR pin or register control |

| PD / PDQ | Power-down control | PD asserts full-device shutdown (3.5 mW typ); PDQ powers down Q-channel only |
| OR+/OR− | Out-of-range indicator | Differential signal indicating input exceeds ±VIN/2; shared for I/Q unless PDQ asserted |
| CalRun | Calibration status indicator | Logic-high during active self-calibration cycle; enables real-time calibration monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC08D1000CIYB | Lower max sample rate (1.0 GSPS dual / 2.0 GSPS interleaved); identical 8-bit resolution and HLQFP-128 package | Targeted at cost-sensitive, lower-bandwidth instrumentation where 1.5 GSPS is not required | Select when full 1.5 GSPS capability is unnecessary and power budget is tighter (1.2 W typ vs. 1.6 W) |
| ADC12D1600RFIUT | 12-bit resolution, 1.6 GSPS dual / 3.2 GSPS interleaved; uses QFN-196 package with different pinout and power sequencing | Used where higher ENOB (>8.5 bits) and wider SFDR (>65 dB) justify added complexity and cost | Choose when system requires >10-bit effective resolution for high-order modulation (e.g., 256-QAM) or radar pulse fidelity |
Compared with ADC08D1520DEV/NOPB, ADC08D1000CIYB trades 500 MSPS headroom for lower power and cost, while ADC12D1600RFIUT provides significantly higher resolution and SFDR but demands more complex layout, thermal management, and power delivery.

FAQ
What is the maximum guaranteed sample rate for ADC08D1520DEV/NOPB in dual-channel mode?
The ADC08D1520DEV/NOPB is specified for up to 1.5 GSPS per channel in dual-channel mode, with guaranteed performance including no missing codes and ≤±0.6 LSB DNL over −40°C to +85°C. Interleaving both channels achieves 3.0 GSPS aggregate throughput, validated per TI SNAS357D Rev. March 2013.
Does ADC08D1520DEV/NOPB support both SDR and DDR LVDS output clocking?
Yes, ADC08D1520DEV/NOPB supports both SDR and DDR LVDS output clocking modes. The OutEdge/DDR/SDATA pin (pin 4) configures this behavior: when floating or at VA/2, DDR mode is enabled. In 1:2 demux mode, DCLK runs at 1/4 input clock rate in DDR mode; in non-demux mode, DCLK operates only in DDR at 1/2 input clock rate.
How does the ADC08D1520DEV/NOPB handle power-down functionality?
The ADC08D1520DEV/NOPB provides two power-down options: asserting PD (pin 26) places the entire device into low-power state consuming 3.5 mW typical, while asserting PDQ (pin 29) powers down only the Q-channel, retaining I-channel operation. Both states preserve register settings and allow fast wake-up without recalibration.
What is the role of the OR+/OR− pins on ADC08D1520DEV/NOPB?
The OR+/OR− pins on ADC08D1520DEV/NOPB provide a differential out-of-range indication signaling when the analog input exceeds ±VIN/2. This flag applies to both I- and Q-channels unless PDQ is asserted, in which case it reflects only the I-channel. The function is selectable via Extended Control Mode registers and defaults to OR mode at power-up.
Can ADC08D1520DEV/NOPB be synchronized with other ADCs for coherent sampling?
Yes, ADC08D1520DEV/NOPB supports deterministic multi-ADC synchronization using its DCLK_RST+/− pins (pins 15 and 14). A differential reset pulse aligns internal clock dividers and phase interpolators across multiple devices, enabling sub-picosecond channel-to-channel skew control essential for phased-array and MIMO systems.
