Product details
Overview
LTC2320IUKG-16#TRPBF from Analog Devices (formerly Linear Technology) is an octal, 16-bit, 1.5 Msps/channel simultaneous-sampling SAR ADC with differential inputs, internal 4.096V reference, ±2 LSB INL typical, 82 dB SNR at 500 kHz, and operation over –40°C to +85°C. It serves as a high-precision data acquisition front-end in multiphase motor control systems requiring synchronized sampling across eight channels.
For engineers reviewing the LTC2320IUKG-16#TRPBF datasheet, LTC2320IUKG-16#TRPBF pinout, LTC2320IUKG-16#TRPBF application, or LTC2320IUKG-16#TRPBF equivalent, key selection considerations include guaranteed 16-bit no-missing-codes performance, LVDS/CMOS serial interface flexibility, simultaneous sampling architecture, low 20 mW/channel power at 1.5 Msps, and QFN-52 package thermal performance for industrial signal conditioning.
Technical Context
The LTC2320IUKG-16#TRPBF implements eight independent SAR ADC cores with shared timing control, enabling true simultaneous sampling across all eight differential input pairs. Each channel features dedicated reference buffers (REFOUT1–4), configurable CMOS or LVDS serial output modes, and SDR/DDR clocking support.
Its internal 4.096V temperature-compensated reference exhibits ≤20 ppm/°C drift and supports external overdrive; analog inputs accept 0 V to VDD common-mode range with ±4.096 V differential full-scale, delivering 102 dB CMRR at 500 kHz and <1 ps RMS aperture jitter for high-fidelity wideband acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with guaranteed no missing codes - ensures unambiguous digital representation of full analog input range without code gaps. |
| Sampling Rate | 1.5 Msps per channel, simultaneous - enables real-time capture of fast transients across eight synchronized channels without inter-channel skew. |
| INL | ±2 LSB typical - limits integral nonlinearity error to <0.003% of full scale, critical for precision measurement linearity. |
| SNR | 82 dB typical at fIN = 500 kHz - delivers >13.3 effective number of bits (ENOB) for high dynamic range signal analysis. |
| Reference | Internal 4.096 V ±20 ppm/°C max - eliminates need for external reference while maintaining accuracy over industrial temperature range. |
| Power | 20 mW per channel at 1.5 Msps - enables dense multi-channel DAQ designs with manageable thermal dissipation in 7 mm × 8 mm QFN. |
| Interface | CMOS or LVDS SPI-compatible serial I/O - supports FPGA interfacing with low EMI (LVDS) or low-voltage logic compatibility (CMOS). |
Pinout & Package
Package: 52-pin (7 mm × 8 mm) plastic QFN with exposed thermal pad (Pin 53 = GND). Pin pitch: 0.5 mm. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– to AIN8+ / AIN8– (Pins 1–2, 4–5, 10–11, 13–14, 16–17, 19–20, 47–48, 50–51) | Eight differential analog input pairs | Each pair accepts ±4.096 V differential range with 0 V to VDD common-mode; enables isolated sensor or transformer-coupled signal acquisition. |
| REFOUT1–REFOUT4 (Pins 22, 9, 6, 45) | Four independent reference buffer outputs | Each drives one or two ADC cores; configurable via REFBUFEN; supports mixed internal/external reference topologies. |
| SDO1–SDO8 (Pins 27–30, 35–36, 39–40) or SDOA±–SDOC± (Pins 27–28, 29–30, 35–36) | Serial data outputs (CMOS or LVDS) | CMOS mode: eight single-ended outputs; LVDS mode: three differential lanes (CH1–2, CH3–4, CH5–6) plus SDO7/SDO8 on dedicated pins - reduces PCB routing complexity. |
| CLKOUT / CLKOUT± (Pin 33 or Pins 33/34) | Skew-matched output clock | Provides deterministic timing for FPGA latch alignment; matches SDO propagation delay to minimize setup/hold violations. |
| REFBUFEN (Pin 43) | Reference buffer enable | Pulled up internally to VDD; grounding disables all REFOUTx buffers to allow external reference injection without conflict. |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous sampling across 8 channels | Eliminates phase skew between channels - essential for vector control in 3-phase motor drives and power quality monitoring. |
| Onboard 4.096 V reference with ≤20 ppm/°C drift | Reduces BOM count and layout sensitivity while maintaining ±10 LSB full-scale error over –40°C to +85°C. |
| Configurable CMOS/LVDS serial interface | Supports both low-power microcontroller interfaces (CMOS, 1.8 V/2.5 V) and high-speed FPGA links (LVDS, 100 Ω termination) without redesign. |
| 1.5 Msps/channel with zero latency | Enables real-time closed-loop control at >100 kHz bandwidth with full 16-bit resolution maintained across all channels. |
| Nap/sleep modes reducing power to 26 μW | Extends operational uptime in battery-backed or energy-constrained industrial IoT edge nodes during idle periods. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7606C-16 | 8-channel, 16-bit, 1 MSPS, internal 2.5 V reference, parallel/serial interface; lower SNR (79 dB), no LVDS option | Better suited for cost-sensitive PLC I/O modules where parallel bus simplifies MCU interfacing | Select when system uses legacy parallel host interfaces and 1 MSPS suffices; avoid if LVDS noise immunity or >1.2 Msps is required. |
| ADS8688 | 8-channel, 16-bit, 500 kSPS, integrated PGA and reference, SPI-only, no simultaneous sampling (multiplexed) | Targeted at programmable logic controller analog input cards with variable gain and lower speed requirements | Choose for designs needing on-chip programmable gain amplifiers and simpler supply sequencing; not suitable for true simultaneous acquisition. |
Compared with AD7606C-16 and ADS8688, the LTC2320IUKG-16#TRPBF uniquely combines 1.5 Msps simultaneous sampling, LVDS output capability, and 4.096 V internal reference stability - making it optimal for FPGA-based high-speed DAQ where timing determinism and noise immunity are critical.

FAQ
What is the operating temperature range for the LTC2320IUKG-16#TRPBF?
The LTC2320IUKG-16#TRPBF is rated for industrial operation from –40°C to +85°C (I-grade). This is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section, where parameters marked with "l" apply across this full range. The device uses thermal design features including an exposed ground pad (Pin 53) to maintain reliability under sustained load at elevated ambient temperatures.
Does the LTC2320IUKG-16#TRPBF support external reference inputs?
Yes, the LTC2320IUKG-16#TRPBF supports external references via REFOUT1–4 pins. When REFBUFEN (Pin 43) is grounded, the internal reference buffers are disabled, allowing external voltages from 1.25 V to 5 V to drive these pins. This configuration is validated in the Internal Reference Characteristics table and Pin Functions description, enabling system-level reference sharing or higher-precision external references.
How many differential input channels does the LTC2320IUKG-16#TRPBF provide?
The LTC2320IUKG-16#TRPBF provides eight fully differential analog input channels (AIN1± through AIN8±), each with independent full-scale range tied to one of four internal reference buffers (REFOUT1–4). This is explicitly stated in the Features list ("Eight Simultaneously Sampling Channels") and verified in the Pin Configuration diagram and Pin Functions section, confirming true simultaneous sampling without multiplexing.
What serial interface modes does the LTC2320IUKG-16#TRPBF support?
The LTC2320IUKG-16#TRPBF supports three serial interface configurations: CMOS (CMOS/LVDS = GND), LVDS (CMOS/LVDS = OVDD), and low-power LVDS (CMOS/LVDS = floating). Each mode supports both SDR and DDR clocking, as documented in the Digital Inputs and Outputs table and Pin Functions section. Timing parameters-including tSCK, tHSDO, and tDSCKCLKOUT-are specified separately for each mode and data rate.
Is the LTC2320IUKG-16#TRPBF pin-compatible with other variants in the LTC2320 family?
Yes, the LTC2320IUKG-16#TRPBF shares identical pinout and package (52-lead QFN) with LTC2320CUKG-16#TRPBF (0°C to 70°C) and LTC2320HUKG-16#TRPBF (–40°C to 125°C), as confirmed in the Order Information table. All variants use the same 2320UKG-16 marking and mechanical dimensions, enabling drop-in replacement across temperature grades without PCB revision.
