Product details
Overview
LTC2266CUJ-14#PBF from Analog Devices (formerly Linear Technology) is a 14-bit, dual-channel, simultaneous-sampling analog-to-digital converter optimized for high-frequency, wide-dynamic-range signal digitization at 80Msps. It delivers 72.9dB SNR and 85dB SFDR at 70MHz input, with ultralow 0.15psRMS aperture jitter, ±1LSB INL (typ), and operates from a single 1.8V supply. It is used in portable medical imaging and multichannel data acquisition systems requiring low power and high fidelity.
For engineers reviewing the LTC2266CUJ-14#PBF datasheet, LTC2266CUJ-14#PBF pinout, LTC2266CUJ-14#PBF application, or LTC2266CUJ-14#PBF equivalent, this page provides verified specifications, package mapping, LVDS serialization modes, temperature-grade validation (0°C to 70°C), and direct alternatives for RF-sampling ADC selection in communications and test equipment.
Technical Context
The LTC2266CUJ-14#PBF implements two independent 14-bit ADC cores with shared PLL-based clocking and integrated sample-and-hold with 800MHz full-power bandwidth. Its differential analog inputs support 1VP–P to 2VP–P selectable ranges via the SENSE pin, and internal reference operation eliminates external voltage references unless higher precision is required.
Digital interface uses serial LVDS outputs configurable in 1-lane (1-bit per channel) or 2-lane (2-bit per channel) mode, with programmable output current (1.75mA or 3.5mA) and optional on-chip 100Ω termination. The SPI port enables runtime configuration of encoding mode, power states (Nap/Sleep), and output formatting without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes over temperature - guarantees monotonicity and full code coverage in demanding measurement applications. |
| Sampling Rate | 80Msps maximum - supports baseband and IF sampling up to Nyquist frequency of 40MHz with minimal aliasing risk. |
| SNR @ 70MHz | 72.9dBFS (typ) - enables >12 effective bits for high-fidelity signal capture in software-defined radios and ultrasound front-ends. |
| SFDR @ 70MHz | 85dBFS (2nd/3rd harmonic) - suppresses spurious content critical for multi-tone cellular base station monitoring. |
| Aperture Jitter | 0.15psRMS - limits sampling uncertainty to <0.01% of period at 100MHz, enabling clean undersampling of IF signals. |
| Power Dissipation | 203mW total (80Msps, 2-lane, 1.75mA mode) - allows thermal management in compact, battery-powered portable medical devices. |
| Analog Supply | Single 1.8V (1.7V–1.9V) - simplifies power delivery and reduces noise coupling versus multi-rail ADCs. |
Pinout & Package
40-pin (6mm × 6mm) plastic QFN package with exposed pad (Pin 41 = GND), rated for 0°C to 70°C operating temperature. Requires soldering of exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+, AIN1– | Channel 1 differential analog input | Accepts 1VP–P to 2VP–P signals; common-mode bias provided by VCM1 (Pin 3). |
| AIN2+, AIN2– | Channel 2 differential analog input | Independent sampling path; matched gain/offset with Channel 1 for coherent dual-channel acquisition. |
| ENC+, ENC– | Differential encode clock input | Supports sine wave, PECL, LVDS, TTL, or CMOS drive; internal duty cycle stabilizer maintains performance across 40%–60% duty cycles. |
| OUT1A+/–, OUT1B+/– | LVDS serial data outputs (Channel 1) | In 2-lane mode: OUT1A carries even bits, OUT1B odd bits; in 1-lane mode only OUT1A active. |
| OUT2A+/–, OUT2B+/– | LVDS serial data outputs (Channel 2) | Same lane assignment as Channel 1; enables time-aligned dual-channel streaming over minimal traces. |
| FR+/–, DCO+/– | Frame start and data clock outputs | FR marks frame boundaries; DCO is source-synchronous clock for LVDS data recovery at FPGA/ASIC receiver. |
| PAR/SER, CS, SCK, SDI | Mode control and SPI interface | PAR/SER selects serial (SPI) or parallel (pin-strapped) configuration; CS/SCK/SDI enable register writes for power modes and output settings. |
| VDD, OVDD, GND, OGND | Analog/digital supplies and grounds | VDD powers ADC core; OVDD powers LVDS drivers; separate OGND minimizes digital switching noise coupling into analog section. |

FAQ
What is the maximum sampling rate supported by the LTC2266CUJ-14#PBF?
The LTC2266CUJ-14#PBF supports a maximum sampling rate of 80Msps, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables. This rate is fixed for the LTC2266-14 speed grade and applies across all operating conditions within its 0°C to 70°C temperature range. Operation above 80Msps is not specified and may result in degraded AC performance or functional failure. The LTC2266CUJ-14#PBF achieves this rate with full 14-bit resolution and no missing codes.
Does the LTC2266CUJ-14#PBF require an external reference voltage?
No, the LTC2266CUJ-14#PBF includes a precision internal reference and does not require an external reference for standard operation. When the SENSE pin is tied to VDD, it configures a ±1V input range with internal reference; grounding SENSE selects ±0.5V. An external reference (0.625V–1.3V) applied to SENSE enables ±0.8×VSENSE range. The internal reference delivers 1.25V ±2.5mV with ±25ppm/°C drift, making external references optional unless tighter tolerance or lower drift is needed.
How many LVDS data lanes does the LTC2266CUJ-14#PBF support, and how are they configured?
The LTC2266CUJ-14#PBF supports both 1-lane and 2-lane LVDS serialization modes. In 2-lane mode (default), each channel outputs two bits per clock cycle on separate differential pairs (e.g., OUT1A+/– and OUT1B+/–). In 1-lane mode, only one pair per channel is active (OUT1A+/– and OUT2A+/–), halving the number of required PCB traces. Mode selection is controlled via the PAR/SER pin and CS pin logic level, with no firmware or SPI command needed for static configuration.
What power-saving modes are available on the LTC2266CUJ-14#PBF?
The LTC2266CUJ-14#PBF offers three power states: Active (203mW at 80Msps), Nap mode (70mW), and Sleep mode (1mW). Nap mode retains register settings and reference bias while disabling ADC cores and LVDS drivers; Sleep mode shuts down nearly all circuitry except wake-up logic. Both modes are entered via SPI register writes or parallel pin control (SDI in parallel mode), enabling rapid resumption (<1µs from Nap, <10µs from Sleep) - ideal for burst-mode acquisition in portable NDT or medical devices.
Is the LTC2266CUJ-14#PBF pin-compatible with other members of the LTC226x family?
Yes, the LTC2266CUJ-14#PBF is pin-compatible with the LTC2267CUJ-14#PBF (105Msps) and LTC2268CUJ-14#PBF (125Msps), as well as their 12-bit counterparts (e.g., LTC2265/LTC2264/LTC2263), all housed in the identical 40-pin 6mm × 6mm QFN package. Pin functions, power domains, and interface signals are identical across the family, allowing drop-in speed upgrades or resolution trade-offs without PCB redesign - a key advantage for scalable platform development.
