Product details
Overview
LTC2193IUKG#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, dual-channel, simultaneous-sampling analog-to-digital converter optimized for high-dynamic-range signal digitization in RF and IF sampling applications. It delivers 76.5dB SNR, 90dB SFDR, ultralow 0.07psRMS jitter, ±2LSB INL (typ), and operates at up to 80Msps with 249mW total power consumption on a single 1.8V supply - enabling high-fidelity data acquisition in portable medical imaging and multi-channel communications systems.
For engineers reviewing the LTC2193IUKG#PBF datasheet, LTC2193IUKG#PBF pinout, LTC2193IUKG#PBF application, or LTC2193IUKG#PBF equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for design-in and long-term sourcing decisions.
Technical Context
The LTC2193IUKG#PBF implements two independent 16-bit ADC cores with shared clocking and serial LVDS output serialization. Its sample-and-hold features 550MHz full-power bandwidth and supports differential or single-ended encode inputs (ENC+/ENC–), with an internal duty cycle stabilizer ensuring performance across wide input duty cycles.
Digital interface includes SPI-configurable serialization modes (1/2/4 bits per channel), programmable LVDS output current (1.75mA or 3.5mA), optional on-chip 100Ω termination, and flexible reference configuration via SENSE pin - supporting internal ±0.5V, ±1V, or external ±0.8×VSENSE input ranges.
Key Specifications

Pinout & Package
Package: 52-pin (7mm × 8mm) plastic QFN with exposed pad (Pin 53 = GND), requiring soldering to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCM1 (1) | Channel 1 common-mode bias output | Nominally VDD/2; used to bias AIN1± inputs - requires 0.1µF bypass to GND for stable DC level. |
| AIN1+, AIN1– (3,4) | Channel 1 differential analog input pair | Accepts 1–2VP-P differential signal; high CMRR (80dB) rejects noise in mixed-signal environments. |
| ENC+, ENC– (17,18) | Differential encode clock inputs | Supports PECL/LVDS/TTL/CMOS; ENC– tied to GND enables single-ended mode - critical for clock tree simplification. |
| OUT1A+/–, OUT1B+/– (43/44, 41/42) | LVDS serialized data outputs (Ch1) | Configurable 1-/2-/4-lane mode; internal 100Ω termination option eliminates external resistors in compact layouts. |
| FR+, FR– (31,32) | Frame start synchronization outputs | Indicates start of new conversion frame - essential for time-aligned multi-ADC capture in phased-array systems. |
| DCO+, DCO– (35,36) | Data clock output pair | LVDS clock synchronized to serialized data - eliminates need for separate clock routing in high-speed interfaces. |
| SENSE (50) | Reference programming input | Sets input range: GND = ±0.5V, VDD = ±1V, external voltage = ±0.8×VSENSE - enables precise full-scale matching across channels. |
Key Features

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 |
|---|---|---|---|
| AD9653BCPZ-80 | 80Msps, 16-bit, dual-channel, JESD204B output (vs LVDS); higher 330mW power; no internal reference | Requires external clock buffer and JESD204B PHY; better suited for high-channel-count backplane systems | Choose AD9653BCPZ-80 when migrating to JESD204B-based FPGA platforms or needing deterministic latency. |
| LTC2263IUKG#PBF | 80Msps, 16-bit, single-channel; identical QFN-52 package and pin-compatible analog interface; lower 145mW power | Lacks second channel and inter-channel matching specs - unsuitable for I/Q or differential measurement | Choose LTC2263IUKG#PBF only for single-channel upgrades where board layout reuse is mandatory and dual-channel functionality is unnecessary. |
Compared with AD9653BCPZ-80 and LTC2263IUKG#PBF, the LTC2193IUKG#PBF uniquely balances dual-channel simultaneity, LVDS simplicity, ultra-low jitter, and industrial temperature support - making it optimal for compact, power-sensitive, time-coherent RF sampling where JESD204B overhead is unjustified.

FAQ
What is the maximum sampling rate supported by the LTC2193IUKG#PBF?
The LTC2193IUKG#PBF supports a maximum sampling rate of 80Msps, as specified in its speed grade designation. This rate is achievable across the full industrial temperature range (–40°C to +85°C) with guaranteed AC performance including 76.5dB SNR and 90dB SFDR at 70MHz input frequency. The device also supports lower rates (down to 5Msps) for power-optimized operation.
Does the LTC2193IUKG#PBF include an internal voltage reference?
Yes, the LTC2193IUKG#PBF includes an internal 1.25V reference (VREF pin) with ±25ppm/°C drift and 1.225V to 1.275V output tolerance. When SENSE is tied to VDD, the internal reference configures a ±1V differential input range; tying SENSE to GND selects ±0.5V. An external reference applied to SENSE sets ±0.8×VSENSE.
How does the serial LVDS interface of the LTC2193IUKG#PBF reduce system complexity?
The LTC2193IUKG#PBF serializes each channel's 16-bit output into 1, 2, or 4 LVDS bit lanes - reducing total data lines from 32 (parallel) to as few as 4. Combined with integrated 100Ω termination and programmable 1.75/3.5mA drive strength, this eliminates external termination resistors and simplifies FPGA interface routing in high-density PCBs.
Can the LTC2193IUKG#PBF operate with a single 1.8V supply?
Yes, the LTC2193IUKG#PBF operates from a single 1.8V analog supply (VDD, pins 15/16/51/52) and a separate 1.8V output driver supply (OVDD, pin 34). Both supplies must be within 1.7V–1.9V. This dual-rail 1.8V architecture isolates analog and digital noise domains while minimizing external regulator count.
What is the purpose of the FR+ and FR– pins on the LTC2193IUKG#PBF?
The FR+ and FR– pins on the LTC2193IUKG#PBF provide a differential frame start signal that asserts at the beginning of each conversion frame. This enables precise synchronization across multiple LTC2193IUKG#PBF devices or with external logic, which is critical for coherent sampling in phased-array radar, multi-channel DAQ, and time-interleaved architectures.
