Texas Instruments ADC08D1500DEV/NOPB

Overview

ADC08D1500DEV/NOPB from Texas Instruments is a dual-channel, 8-bit, 1.5 GSPS analog-to-digital converter with folding-interpolating architecture, delivering 7.25 ENOB at 748 MHz input and 10⁻¹⁸ bit error rate. It operates from a single +1.9 V ±0.1 V supply, consumes 1.8 W typical, and supports SDR/DDR LVDS outputs for high-speed data acquisition in RF and instrumentation systems.

For engineers reviewing the ADC08D1500DEV/NOPB datasheet, ADC08D1500DEV/NOPB pinout, ADC08D1500DEV/NOPB application, or ADC08D1500DEV/NOPB equivalent, key selection criteria include interleave-capable dual-ADC timing alignment, guaranteed no-missing-codes performance across −40°C to +85°C, LVDS output common-mode adjustability (0.8–1.2 V), and on-command self-calibration with external REXT bias.

Technical Context

The ADC08D1500DEV/NOPB implements a fully differential folding-and-interpolating architecture with integrated sample-and-hold amplifiers and self-calibration logic, enabling flat dynamic response beyond Nyquist. Its dual independent 8-bit converters each feature 1:2 LVDS demultiplexing, supporting both standalone operation and interleaved 3 GSPS mode via DCLK_RST synchronization.

It provides two distinct operational modes: Normal Mode (FSR/ECE pin-controlled full-scale range and SDR/DDR clocking) and Extended Control Mode (serial interface register access for fine input offset/full-scale adjustment, DES enable, and calibration delay control). Input acquisition occurs on the falling edge of CLK+, with duty-cycle-corrected sampling ensured by internal clock generation.

Key Specifications

Pinout & Package

The ADC08D1500DEV/NOPB is housed in a 128-lead thermally enhanced exposed-pad HLQFP package. The exposed thermal pad must be soldered to a solid ground plane to ensure rated thermal performance (θJ-PAD = 2.8°C/W) and signal integrity.

FAQ

What is the maximum input clock frequency supported by the ADC08D1500DEV/NOPB?

The ADC08D1500DEV/NOPB supports a maximum input clock frequency of 1.7 GHz in Normal Mode and 1.5 GHz minimum in both Normal and Dual Edge Sampling (DES) modes. Operation at 1.5 GHz is specified for all key dynamic parameters including ENOB, SINAD, and SFDR, with guaranteed performance across the industrial temperature range (−40°C to +85°C).

Does the ADC08D1500DEV/NOPB require external reference components?

No, the ADC08D1500DEV/NOPB integrates an internal bandgap reference (VBG pin) and does not require external reference ICs. However, it does require a precision 3.3 kΩ ±0.1% resistor connected to REXT (pin 32) to set calibration timing. VBG is internally generated and can be left floating or used as a 1.26 V reference source with ±28 ppm/°C drift.

How is interleave mode configured between two ADC08D1500DEV/NOPB devices?

Interleave mode is configured by connecting the DCLK_RST pins of both ADC08D1500DEV/NOPB devices to a common synchronous reset signal. This aligns the internal clock dividers and sampling phases, enabling coherent 3 GSPS operation. The DES pin (127) must be left floating on both units, and the FSR/ECE pins must be set identically to maintain matched full-scale ranges.

What LVDS output voltage levels does the ADC08D1500DEV/NOPB support?

The ADC08D1500DEV/NOPB supports two LVDS output amplitude modes: normal (400–920 mVP-P differential) when OutV/SCLK (pin 3) is tied high, and reduced-power (280–720 mVP-P) when pin 3 is grounded. The common-mode voltage is adjustable from 0.8 V to 1.2 V via VCMO pin configuration, ensuring compatibility with diverse FPGA and ASIC receiver inputs.

Is the ADC08D1500DEV/NOPB RoHS compliant and lead-free?

Yes, the ADC08D1500DEV/NOPB is RoHS compliant and lead-free. The "/NOPB" suffix explicitly denotes lead-free packaging per JEDEC J-STD-609. The HLQFP-128 package uses matte tin lead finish and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements.
