Product details
Overview
LTC2263IUJ-12#PBF from Analog Devices (formerly Linear Technology) is a 12-bit, dual-channel, simultaneous-sampling analog-to-digital converter optimized for high-frequency signal digitization at 25Msps. It delivers 70.5dB SNR and 90dB SFDR at 70MHz input, with ultralow 0.15psRMS aperture jitter, ±0.3LSB INL (typ), and operates from a single 1.8V supply. It serves in portable medical imaging front-ends requiring low-power, high-dynamic-range digitization of differential analog signals.
For engineers reviewing the LTC2263IUJ-12#PBF datasheet, LTC2263IUJ-12#PBF pinout, LTC2263IUJ-12#PBF application, or LTC2263IUJ-12#PBF equivalent, this page provides verified specifications, QFN-40 package layout, LVDS serialization modes, temperature-grade validation (–40°C to +85°C), and direct alternatives for multichannel data acquisition and software-defined radio receiver designs.
Technical Context
The LTC2263IUJ-12#PBF implements two independent 12-bit ADC cores with shared PLL-based sampling clock generation and integrated duty-cycle stabilizer-enabling robust performance across wide encode duty cycles. Its analog front-end features 800MHz full-power bandwidth sample-and-hold and supports 1VP-P to 2VP-P differential input ranges via SENSE pin configuration.
Digital interface uses serial LVDS outputs with selectable 1-lane or 2-lane mode per channel, internal 100Ω termination, and adjustable output current (1.75mA/3.5mA). Configuration is handled via SPI port or parallel logic inputs (PAR/SER mode), supporting shutdown and nap modes for dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

FAQ
What is the operating temperature range of the LTC2263IUJ-12#PBF?
The LTC2263IUJ-12#PBF is specified for industrial operation from –40°C to +85°C. This grade is confirmed in the Absolute Maximum Ratings table and Order Information section of the datasheet, with the "I" suffix denoting the extended temperature range. The device maintains full performance-including 70.5dB SNR and ±0.3LSB INL-across this entire range when powered from 1.8V supplies.
Does the LTC2263IUJ-12#PBF support external reference configuration?
Yes, the LTC2263IUJ-12#PBF supports external reference via the SENSE pin. Applying a voltage between 0.625V and 1.3V to SENSE selects an external reference mode, enabling custom input ranges and improved system-level accuracy. The datasheet specifies transition noise of 0.32LSBRMS and gain matching of ±0.2%FS under external reference conditions-critical for multichannel calibration.
How many LVDS data lanes does the LTC2263IUJ-12#PBF support, and how are they configured?
The LTC2263IUJ-12#PBF supports both 1-lane and 2-lane LVDS serialization per channel, selected via the CS pin in parallel programming mode (PAR/SER = VDD). In 2-lane mode, it outputs two bits per clock edge per channel; in 1-lane mode, one bit per edge. Both modes use the same OUT1A+/–, OUT1B+/–, OUT2A+/–, and OUT2B+/– pins, with output current (1.75mA or 3.5mA) set by SCK.
What is the significance of the "UJ" package designation in LTC2263IUJ-12#PBF?
The "UJ" in LTC2263IUJ-12#PBF denotes a 40-lead, 6mm × 6mm plastic QFN package with exposed thermal pad (Pin 41 = GND). This package is thermally optimized for low-power ADCs, providing 32°C/W junction-to-ambient thermal resistance. The datasheet mandates soldering the exposed pad to the PCB ground plane for reliable thermal performance and signal integrity in high-frequency applications.
Can the LTC2263IUJ-12#PBF be used with single-ended encode clock inputs?
Yes, the LTC2263IUJ-12#PBF accepts single-ended encode clocks by tying ENC– to GND and driving ENC+ with TTL, CMOS, or 1.8V square wave signals. The datasheet specifies VIH = 1.2V and VIL = 0.6V for ENC+ under these conditions, with input resistance of 30kΩ and capacitance of 3.5pF-enabling direct connection to FPGA or microcontroller GPIO without level-shifting circuitry.
