Product details
Overview
LTC2182CUP#PBF 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 aperture jitter, enabling undersampling of IF signals up to 140MHz in cellular base stations and software-defined radios.
For engineers reviewing the LTC2182CUP#PBF datasheet, LTC2182CUP#PBF pinout, LTC2182CUP#PBF application, or LTC2182CUP#PBF equivalent, key selection factors include its 64-pin QFN package, 1.8V single-supply operation, selectable CMOS/DDR-CMOS/DDR-LVDS output interfaces, and support for differential or single-ended clock inputs with duty cycle stabilization.
Technical Context
The LTC2182CUP#PBF implements two independent 16-bit ADC cores sharing a common sample-and-hold with 550MHz full-power bandwidth, enabling true simultaneous sampling across channels. Its internal reference provides 1.25V ±25ppm/°C stability, while external reference mode supports SENSE pin input from 0.625V to 1.3V.
Digital interface flexibility includes serial SPI configuration, programmable output data format (two's complement or offset binary), optional data randomization to reduce spectral spurs, and low-power Nap (10mW) and Sleep (1mW) modes. Clock encoding supports both differential (ENC+/ENC–) and single-ended (ENC+ only) operation with configurable timing constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with no missing codes over temperature - guarantees monotonicity and full code coverage in precision measurement systems. |
| Sampling Rate | 65Msps - enables real-time digitization of wideband IF signals up to 140MHz using undersampling techniques. |
| SNR | 77dB at 70MHz input - ensures high-fidelity signal reconstruction in demanding RF receiver chains. |
| SFDR | 90dB at 70MHz input - suppresses harmonic distortion critical for multi-carrier cellular and radar applications. |
| Aperture Jitter | 0.07psRMS - minimizes sampling uncertainty, directly enabling high-IF sampling without external jitter cleanup. |
| Power Dissipation | 160mW total at 65Msps with CMOS outputs - balances performance and thermal management in dense PCB layouts. |
| Analog Supply | Single 1.8V (1.7V–1.9V) - simplifies power delivery and reduces board-level DC-DC complexity. |
Pinout & Package
64-lead (9mm × 9mm) plastic QFN package with exposed thermal pad (Pin 65 = GND). Requires soldering of exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 16-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9269BCPZ-65 | 65Msps, 16-bit, single-channel; requires external clock distribution for dual-channel sync. | Lacks native simultaneous sampling; needs external circuitry for channel alignment. | Choose when system already uses ADI ecosystem and channel count can be met with two separate converters. |
| ADS52J90IRGCT | 65Msps, 16-bit, 8-channel; lower SNR (74dB) and higher power (540mW). | Higher channel density but reduced dynamic range and increased thermal load. | Prefer for multi-channel systems where board space is constrained and SNR >75dB is acceptable. |
Compared with AD9269BCPZ-65 and ADS52J90IRGCT, the LTC2182CUP#PBF uniquely integrates true simultaneous sampling, lower power (160mW), and superior SFDR (90dB), making it optimal for phase-sensitive, power-constrained dual-channel applications like portable ultrasound and compact SDRs.

FAQ
What is the operating temperature range for the LTC2182CUP#PBF?
The LTC2182CUP#PBF is specified for commercial-grade operation from 0°C to 70°C. This is indicated by the "C" suffix in the part number and confirmed in the Absolute Maximum Ratings table. For extended temperature operation (–40°C to 85°C), the LTC2182IUP#PBF variant is available.
Does the LTC2182CUP#PBF support external voltage reference?
Yes, the LTC2182CUP#PBF supports external reference mode via the SENSE pin (Pin 63), which accepts an input from 0.625V to 1.3V. When used, the internal 1.25V reference is disabled, allowing precise system-level reference control and improved temperature stability when paired with a high-accuracy external source.
How does the PAR/SER pin affect configuration of the LTC2182CUP#PBF?
The PAR/SER pin (Pin 11) selects programming mode: grounded for serial SPI control (using CS/SCK/SDI/SDO), or tied to VDD for parallel logic control. In serial mode, all device features-including output format, randomizer, and duty cycle stabilizer-are fully configurable; parallel mode offers limited control over key functions only.
What output interface options does the LTC2182CUP#PBF support?
The LTC2182CUP#PBF supports three digital output modes: full-rate CMOS, double-data-rate CMOS, and double-data-rate LVDS. Output voltage levels are set by OVDD (Pin 42), which can be 1.2V, 1.5V, or 1.8V for CMOS modes, or 1.7V–1.9V for LVDS mode with integrated 100Ω termination.
Can the LTC2182CUP#PBF operate with a single-ended clock input?
Yes, the LTC2182CUP#PBF supports single-ended clock operation by tying ENC– (Pin 19) to GND and driving ENC+ (Pin 18) with a 1.8V square wave. The datasheet specifies VIH ≥1.2V and VIL ≤0.6V for reliable single-ended encoding at 65Msps, with timing parameters validated under this configuration.
