Product details
Overview
LTC2182IUP#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 65Msps dual-channel simultaneous-sampling analog-to-digital converter optimized for high-dynamic-range signal digitization in communications infrastructure. It delivers 77dB SNR, 90dB SFDR, and ultralow 0.07psRMS jitter, enabling undersampling of IF signals up to 140MHz in cellular base stations and software-defined radios.
For engineers reviewing the LTC2182IUP#TRPBF datasheet, LTC2182IUP#TRPBF pinout, LTC2182IUP#TRPBF application, or LTC2182IUP#TRPBF equivalent, key selection criteria include its dual-channel synchronization capability, selectable CMOS/DDR-CMOS/DDR-LVDS output interfaces, 1.8V single-supply operation, 550MHz full-power bandwidth, and industrial-temperature (–40°C to +85°C) QFN packaging.
Technical Context
The LTC2182IUP#TRPBF employs a two-channel simultaneous sampling architecture with independent sample-and-hold circuits, ensuring precise channel-to-channel timing alignment critical for I/Q demodulation and beamforming. Its internal reference supports both internal (1.25V) and external SENSE-based voltage referencing, with ±25ppm/°C drift and 7Ω output impedance.
Digital interface flexibility includes serial SPI configuration, programmable clock duty cycle stabilization, optional data randomization, and three output modes-full-rate CMOS, DDR-CMOS, and DDR-LVDS-with separate OVDD supply (1.1V–1.9V) enabling level-shifting compatibility across logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, no missing codes over temperature - guarantees monotonicity and full dynamic range utilization in precision measurement. |
| Sampling Rate | 65Msps - enables real-time digitization of wideband IF signals up to 140MHz via undersampling. |
| SNR / SFDR | 77dB / 90dB at 70MHz input - provides high-fidelity signal capture for demanding wireless standards like LTE and 5G NR. |
| Input Bandwidth | 550MHz full-power - supports direct RF sampling of UHF bands without external amplification or filtering. |
| Power Dissipation | 160mW total at 65Msps (CMOS mode) - enables dense multi-channel ADC arrays in power-constrained baseband units. |
| Supply Voltage | Single 1.8V analog (VDD) and configurable 1.1V–1.9V digital (OVDD) - simplifies power delivery and reduces board-level DC/DC count. |
| Operating Temp | –40°C to +85°C - qualified for industrial and outdoor telecom equipment deployment. |
Pinout & Package
64-pin (9mm × 9mm) plastic QFN package with exposed thermal pad (Pin 65 = GND), requiring soldering to PCB for thermal and electrical integrity. Pin numbering follows standard UP top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (1,16,17,64) | Analog supply input | 1.7V–1.9V analog rail; requires local 0.1µF ceramic bypass per group to ensure low-noise conversion. |
| AIN1+/AIN1– (4,5) | Channel 1 differential analog input | Accepts 1VP-P to 2VP-P differential signals; biased by VCM1 (Pin 2) at VDD/2 for optimal common-mode rejection. |
| ENC+/ENC– (18,19) | Differential encode clock input | Supports sine wave, LVDS, PECL, TTL, or CMOS clocks; ENC– tied to GND enables single-ended mode. |
| PAR/SER (11) | Programming mode select | Ground = serial SPI control; VDD = parallel logic control - determines whether CS/SCK/SDI/SDO function as serial interface or discrete mode pins. |
| D1_0–D1_15 / D2_0–D2_15 (43–58, 23–32) | Dual-channel digital outputs | Configurable as full-rate CMOS, DDR-CMOS, or DDR-LVDS; output swing set by OVDD (Pin 42) and mode selection. |
| REFH/REFL (7,8,9,10) | ADC reference terminals | Internal 1.25V reference with ±25ppm/°C drift; REFL tied to ground when using internal reference; REFH/REFL require 10µF + 0.1µF bypassing. |
| SENSE (63) | External reference input | Accepts 0.625V–1.3V external reference for improved gain accuracy and temperature stability vs. internal reference. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 16-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9269BCPZ-65 | 65Msps, 16-bit, single-channel only; requires external clock distribution and interleaving for dual-channel use. | Lacks native simultaneous sampling; adds complexity and timing skew risk in I/Q systems. | Choose when single-channel density or legacy ADI ecosystem integration outweighs dual-channel synchronization needs. |
| ADS52J90IRGCT | 65Msps, 16-bit, quad-channel with JESD204B interface; higher power (525mW) and larger 72-pin QFN package. | Targets high-channel-count systems with FPGA/JESD204B backhaul; not drop-in compatible due to interface and pinout differences. | Prefer for scalable multi-ADC systems requiring deterministic latency and serializer interface, not for standalone dual-channel designs. |
Compared with AD9269BCPZ-65 and ADS52J90IRGCT, the LTC2182IUP#TRPBF uniquely integrates true simultaneous sampling, ultra-low jitter, and flexible output interfaces in a compact 64-pin QFN - delivering lower system-level timing complexity and reduced BOM count for dual-channel IF digitization.

FAQ
What is the maximum analog input frequency supported by the LTC2182IUP#TRPBF?
The LTC2182IUP#TRPBF features a 550MHz full-power bandwidth, enabling reliable digitization of analog inputs up to 550MHz. At 65Msps sampling, this supports undersampling of IF signals such as 70MHz, 140MHz, or higher frequencies while maintaining 77dB SNR and 90dB SFDR performance as specified in the datasheet.
Does the LTC2182IUP#TRPBF support external voltage reference operation?
Yes, the LTC2182IUP#TRPBF supports external reference operation via the SENSE pin (Pin 63), which accepts 0.625V–1.3V. When used, it replaces the internal 1.25V reference and improves gain accuracy and temperature stability - particularly valuable in precision measurement systems where reference drift must be minimized.
How does the LTC2182IUP#TRPBF handle clock jitter sensitivity?
The LTC2182IUP#TRPBF achieves 0.07psRMS aperture jitter, among the lowest in its class. This enables high-SNR undersampling of high-frequency IF signals without requiring ultra-low-jitter external clock sources or dedicated jitter cleaners - reducing system cost and board space in base station and SDR applications.
Can the LTC2182IUP#TRPBF operate with a single 1.8V supply?
Yes, the LTC2182IUP#TRPBF operates from a single 1.8V analog supply (VDD) and supports a separate 1.1V–1.9V digital output supply (OVDD). This allows direct interfacing with 1.2V, 1.5V, or 1.8V logic families without level shifters, while maintaining analog performance integrity through independent power domains.
What output interface modes does the LTC2182IUP#TRPBF support?
The LTC2182IUP#TRPBF supports three configurable digital output modes: full-rate CMOS, double-data-rate CMOS (DDR-CMOS), and double-data-rate LVDS (DDR-LVDS). Mode selection is controlled via the PAR/SER pin and SCK, allowing trade-offs between power efficiency (CMOS), pin count reduction (DDR-CMOS), and noise immunity (DDR-LVDS) based on system requirements.
