Product details
Overview
LTC2320CUKG-16#PBF from Analog Devices (formerly Linear Technology) is an octal, 16-bit, 1.5 Msps/channel simultaneous-sampling SAR ADC with differential inputs, internal 4.096 V reference, ±2 LSB INL (typ), 82 dB SNR at 500 kHz, and operation from a single 3.3 V or 5 V supply. It serves as the high-precision front-end digitizer in multiphase motor control systems requiring synchronized acquisition across eight channels.
For engineers reviewing the LTC2320CUKG-16#PBF datasheet, LTC2320CUKG-16#PBF pinout, LTC2320CUKG-16#PBF application, or LTC2320CUKG-16#PBF equivalent, key selection considerations include guaranteed 16-bit no-missing-codes performance, LVDS/CMOS dual-mode serial interface support, 52-pin QFN package thermal and layout constraints, and temperature-grade–specific timing stability up to 70°C.
Technical Context
The LTC2320CUKG-16#PBF implements eight independent SAR ADC cores sharing a common sampling aperture, enabling true simultaneous capture with <500 ps aperture delay matching. Each channel features fully differential input pairs (AINx+, AINx–) referenced to dedicated buffered outputs (REFOUT1–REFOUT4), supporting bipolar ±4.096 V full-scale ranges with 102 dB CMRR at 500 kHz.
Its SPI-compatible serial interface operates in CMOS (1.8 V–2.5 V OVDD) or LVDS (2.5 V OVDD) mode, selectable via the CMOS/LVDS pin, and supports both SDR and DDR clocking-enabling 16-bit data readout per channel in 8 SCK cycles (DDR) or 16 SCK cycles (SDR). Internal reference buffer enable (REFBUFEN) allows seamless transition to external references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonic transfer function and no missing codes across full operating temperature range (0°C to 70°C). |
| Sampling Rate | 1.5 Msps per channel - enables real-time capture of signals up to ~55 MHz bandwidth (–3 dB input BW) without interleaving artifacts. |
| SNR / SINAD | 82.2 dB / 81.8 dB at fIN = 500 kHz - delivers >13.3 effective number of bits (ENOB) for high-fidelity signal reconstruction. |
| INL / DNL | ±2 LSB (typ) / ±0.4 LSB (typ) - ensures accurate amplitude linearity critical for closed-loop control and spectral analysis. |
| Reference | Internal 4.096 V ±20 ppm/°C max - eliminates need for external precision reference and reduces BOM count in space-constrained designs. |
| Power Dissipation | 102 mW (3.3 V, CMOS, 1.5 Msps) - enables thermally constrained embedded DAQ systems without active cooling. |
| Package | 52-pin (7 mm × 8 mm) QFN with exposed pad - provides low thermal resistance (θJA = 29°C/W) and robust ground integrity for high-speed analog performance. |
Pinout & Package
Package: 52-lead plastic QFN (7 mm × 8 mm), exposed pad (Pin 53) soldered to PCB ground plane for thermal and electrical integrity.
| 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 swing with wide common-mode range (0 V to VDD); matched routing required for phase coherence. |
| REFOUT1–REFOUT4 (Pins 22, 9, 6, 45) | Dedicated reference buffer outputs | Provide isolated 4.096 V references per ADC quadrant; decoupling with 10 µF X5R ceramic capacitors essential for noise immunity. |

| CMOS/LVDS (Pin 25), SDR/DDR (Pin 23) | Interface configuration controls | Hardware-strapped pins determine I/O voltage standard and data capture edge count-no register programming needed. |
| CNV (Pin 24) | Convert initiation input | Edge-triggered (OVDD-level) signal starts simultaneous sampling; low-jitter source required to minimize aperture uncertainty. |
Key Features
| Feature | Design Value |
|---|---|
| Octal simultaneous sampling | Eliminates inter-channel skew in multiphase current/voltage sensing-critical for vector control accuracy and harmonic analysis. |
| Onboard 4.096 V reference with 20 ppm/°C drift | Reduces system-level calibration burden and improves long-term gain stability over temperature without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal, 16-bit, simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7606C-16 (Analog Devices) | 16-bit, 8-channel, 1 Msps/channel; uses charge redistribution SAR; integrated analog front-end with PGA and anti-alias filter. | Better suited for lower-speed, sensor-conditioning applications requiring programmable gain and on-chip filtering. | Select AD7606C-16 when system-level signal conditioning (e.g., ±10 V inputs, 2×/4×/8× PGA) is required alongside digitization. |
| ADS8688 (Texas Instruments) | 16-bit, 8-channel, 500 ksps/channel; successive approximation with integrated reference and SPI interface; 1.8 V to 3.3 V I/O compatible. | Targeted at cost-sensitive industrial PLC modules where throughput <1 Msps suffices and lower power (45 mW) is prioritized. | Select ADS8688 for compact, low-power distributed I/O nodes where 500 ksps/channel meets control loop timing budgets. |
Compared with AD7606C-16 and ADS8688, the LTC2320CUKG-16#PBF delivers 50% higher per-channel throughput (1.5 Msps vs. 1 Msps/500 ksps), superior dynamic performance (82.2 dB SNR vs. 80 dB/78.2 dB), and hardware-configurable LVDS/CMOS I/O-making it optimal for high-fidelity, time-critical acquisition where deterministic latency and phase coherence are non-negotiable.

FAQ
What is the maximum sampling rate per channel for the LTC2320CUKG-16#PBF?
The LTC2320CUKG-16#PBF achieves a maximum sampling rate of 1.5 Msps per channel, with guaranteed timing across all eight simultaneously sampled channels. This rate is supported in both CMOS and LVDS interface modes, and conversion time remains fixed at 450 ns regardless of temperature or supply voltage within specified operating conditions.
Does the LTC2320CUKG-16#PBF require an external reference voltage?
No, the LTC2320CUKG-16#PBF integrates a low-drift 4.096 V temperature-compensated reference with ≤20 ppm/°C drift, eliminating the need for an external reference in most applications. The REFBUFEN pin allows disabling internal buffers if an external reference (1.25 V to 5 V) is preferred, but the LTC2320CUKG-16#PBF operates fully functional with its internal reference enabled.
How many analog input channels does the LTC2320CUKG-16#PBF support, and are they truly simultaneous?
The LTC2320CUKG-16#PBF supports eight fully differential analog input channels (AIN1+/- through AIN8+/-), and sampling is truly simultaneous across all channels. Its architecture uses a shared sampling aperture and matched track-and-hold circuits, delivering <500 ps aperture delay matching-verified across the 0°C to 70°C operating range of the LTC2320CUKG-16#PBF.
What digital interface options does the LTC2320CUKG-16#PBF support?
The LTC2320CUKG-16#PBF supports both CMOS and LVDS serial interfaces, selected via the CMOS/LVDS pin. Each mode further supports Single Data Rate (SDR) and Double Data Rate (DDR) clocking, controlled by the SDR/DDR pin. In DDR mode, 16-bit data per channel is transferred in just 8 SCK cycles-reducing host controller timing demands while maintaining signal integrity.
What is the operating temperature range for the LTC2320CUKG-16#PBF?
The LTC2320CUKG-16#PBF is rated for operation from 0°C to 70°C (commercial grade), as indicated by the "C" suffix in its part number. Electrical specifications-including INL, SNR, and timing parameters-are guaranteed across this full range. For extended temperature operation, alternative variants such as LTC2320IUKG-16#PBF (–40°C to 85°C) or LTC2320HUKG-16#PBF (–40°C to 125°C) are available.
