Product details
Overview
ADC08D1020CIYB/NOPB from Texas Instruments is a dual, low-power, 8-bit CMOS analog-to-digital converter capable of 1.0 GSPS per channel (2.0 GSPS interleaved), operating from a single +1.9 V ±0.1 V supply, delivering 7.4 ENOB at 498 MHz input with 10⁻¹⁸ code error rate, and used in direct RF down-conversion systems requiring high-speed digitization with LVDS output compatibility.
For engineers reviewing the ADC08D1020CIYB/NOPB datasheet, ADC08D1020CIYB/NOPB pinout, ADC08D1020CIYB/NOPB application, or ADC08D1020CIYB/NOPB equivalent, key selection considerations include its dual-channel 1 GSPS operation, 1:1/1:2 selectable LVDS demux, interleave synchronization capability, and industrial-temperature (−40°C to +85°C) HLQFP-128 packaging with exposed thermal pad.
Technical Context
The ADC08D1020CIYB/NOPB employs a folding-and-interpolating architecture with fully differential comparators and an innovative sample-and-hold amplifier, enabling flat dynamic performance beyond Nyquist and supporting direct RF sampling up to 2.0 GHz full-power bandwidth. Its calibration schemes ensure no missing codes across temperature and process variation.
It supports three operational modes: independent dual-channel (1.0 GSPS each), interleaved single-channel (2.0 GSPS), and dual-edge sampling (DES) mode for 1.3 GSPS with 1:4 demux. Output formatting is offset binary LVDS compliant with IEEE 1596.3–1996, with adjustable common-mode voltage (0.8–1.2 V) and selectable SDR/DDR clocking.

Pinout & Package
The ADC08D1020CIYB/NOPB is housed in a thermally enhanced, lead-free 128-lead HLQFP package with an exposed pad on the bottom side that must be soldered to a ground plane for rated thermal and electrical performance (θJC = 2.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+/CLK− | Differential clock input | Samples analog input on falling edge of CLK+; requires AC coupling and 0.4–2.0 VP-P amplitude |

FAQ
What is the maximum guaranteed sample rate for ADC08D1020CIYB/NOPB in dual-channel mode?
The ADC08D1020CIYB/NOPB guarantees 1.0 GSPS per channel in independent dual-channel mode, with full specifications including ENOB, SINAD, and SFDR validated at this rate. Interleaved operation achieves 2.0 GSPS, but the minimum specified conversion rate remains 1.0 GSPS per channel per the datasheet's "Max Conversion Rate" parameter.
Does ADC08D1020CIYB/NOPB support DC-coupled analog inputs?
Yes, ADC08D1020CIYB/NOPB supports both AC- and DC-coupled analog inputs. For DC coupling, the VCMO pin must be driven to the required common-mode voltage (typically 1.0 V), and the input common-mode range is specified as VCMO ±50 mV. The full-scale differential input range remains programmable (650–940 mVP-P) regardless of coupling method.
How does the Power Down (PDQ) pin affect ADC08D1020CIYB/NOPB functionality?
A logic high on the PDQ pin places the entire ADC08D1020CIYB/NOPB into Power Down Mode, reducing consumption to 3.5 mW typical while retaining register settings. All analog and digital outputs go high-impedance, and internal clocks halt. Exit time is less than 1 µs after PDQ returns low, enabling rapid wake-up for burst-mode acquisition.
Can ADC08D1020CIYB/NOPB synchronize multiple converters using a shared clock?
Yes, ADC08D1020CIYB/NOPB supports precise multi-ADC synchronization via its DCLK_RST+/DCLK_RST− pins. A differential reset pulse aligns the phase of DCLK outputs across multiple devices, ensuring deterministic inter-channel timing for interleaved or parallel sampling architectures - critical for phased-array and MIMO systems.
What LVDS output configuration options does ADC08D1020CIYB/NOPB provide?
ADC08D1020CIYB/NOPB offers selectable SDR or DDR output clocking, 1:1 or 1:2 output demultiplexing, and adjustable LVDS common-mode voltage (0.8–1.2 V). In 1:2 demux mode, it delivers two time-aligned 8-bit LVDS data streams per channel (DI/DQ and DId/DQd), each at half the sample rate, easing FPGA capture timing closure.
