Product details
Overview
LTC2320HUKG-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 up to 125°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 LTC2320HUKG-16#PBF datasheet, LTC2320HUKG-16#PBF pinout, LTC2320HUKG-16#PBF application, or LTC2320HUKG-16#PBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, simultaneous sampling architecture, LVDS/CMOS serial interface flexibility, wide common-mode input range (0 V to VDD), and extended temperature grade (–40°C to 125°C).
Technical Context
The LTC2320HUKG-16#PBF implements eight independent SAR ADC cores, each with dedicated sample-and-hold, enabling true simultaneous acquisition across all channels without inter-channel skew. Its internal reference buffers (REFOUT1–REFOUT4) support independent voltage scaling per channel group, and the CMOS/LVDS mode select pin enables interface optimization for noise immunity or power efficiency.
Timing is governed by a single CNV pulse that initiates conversion across all channels; readout occurs via high-speed SPI-compatible serial interface supporting SDR/DDR modes and configurable clock polarity. Aperture jitter is specified at 1 ps RMS, and aperture delay matching between channels is ≤500 ps - critical for coherent multi-channel signal analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, guaranteed no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Sampling Rate | 1.5 Msps per channel, simultaneous - enables real-time capture of fast transients across 8 channels without time-interleaving artifacts. |
| SNR | 82 dB (typ) at fIN = 500 kHz - supports >13.3 effective bits for high-fidelity signal reconstruction in demanding applications. |
| INL | ±2 LSB (typ), –12/+12 LSB (max) - maintains linearity accuracy essential for closed-loop control and calibration-sensitive systems. |
| Reference | Internal 4.096 V ±0.4% (typ), 20 ppm/°C max drift - eliminates external reference component count while ensuring stable scaling over temperature. |
| Supply | Single 5 V (4.75–5.25 V) or 3.3 V (3.13–3.47 V); OVDD = 1.71–2.63 V - simplifies power architecture with flexible I/O voltage for FPGA/ASIC interfacing. |
| Power | 20 mW per channel (typ) at 1.5 Msps; sleep mode draws 26 µW - enables low-power operation during idle cycles without sacrificing active performance. |
Pinout & Package
The LTC2320HUKG-16#PBF is housed in a 52-lead (7 mm × 8 mm) plastic QFN package with exposed thermal pad (Pin 53) soldered to PCB ground. Pin functions are defined per digital I/O mode (CMOS/LVDS), with dedicated analog input pairs, reference outputs, and configurable serial interface pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– to AIN8+ / AIN8– | Differential analog inputs (8 channels) | Each pair accepts ±REFOUTx differential input range; supports wide common-mode (0 V to VDD) for direct connection to isolated amplifiers or sensors. |
| REFOUT1–REFOUT4 | Independent reference buffer outputs | Four 4.096 V buffered references enable per-group gain scaling; REFBUFEN disables buffers for external reference injection. |
| SDO1–SDO8 (CMOS) or SDOA±–SDOD± (LVDS) | Serial data outputs | Eight independent CMOS outputs or four differential LVDS lanes allow flexible FPGA interface; DDR mode halves required clock frequency. |
| CNV | Convert initiation input | Rising edge triggers simultaneous sampling across all channels; timing-critical - requires low-jitter OVDD-level signal. |
| CMOS/LVDS & SDR/DDR | Interface configuration pins | Hardware-selectable I/O standard and data rate mode - eliminates firmware configuration overhead and ensures deterministic timing. |

FAQ
What is the maximum operating temperature for the LTC2320HUKG-16#PBF?
The LTC2320HUKG-16#PBF is rated for operation from –40°C to +125°C, with full electrical specifications guaranteed across this extended industrial temperature range. This makes it suitable for under-hood automotive, downhole, and high-ambient industrial environments where standard commercial-grade ADCs would fail or require derating.
Does the LTC2320HUKG-16#PBF require an external reference?
No, the LTC2320HUKG-16#PBF includes an onboard low-drift (20 ppm/°C max) 4.096 V temperature-compensated reference buffer. REFBUFEN can be tied to VDD to enable internal reference operation; grounding REFBUFEN disables the buffers for external reference use - providing design flexibility without mandatory external components.
How does the simultaneous sampling architecture work in the LTC2320HUKG-16#PBF?
The LTC2320HUKG-16#PBF uses eight independent sample-and-hold circuits and SAR ADC cores, all triggered by a single CNV pulse. This ensures true simultaneous acquisition across all eight channels with aperture delay matching ≤500 ps - eliminating time skew that would corrupt phase relationships in multi-sensor or multi-phase measurements.
What digital interface options does the LTC2320HUKG-16#PBF support?
The LTC2320HUKG-16#PBF supports both CMOS and LVDS serial interfaces, selected via the CMOS/LVDS pin. Each mode supports Single Data Rate (SDR) and Double Data Rate (DDR) operation, controlled by the SDR/DDR pin. LVDS mode provides superior noise immunity for long traces or noisy environments, while CMOS offers lower power and simpler termination.
Can the LTC2320HUKG-16#PBF operate from a 3.3 V supply?
Yes, the LTC2320HUKG-16#PBF operates from either a 3.3 V (3.13–3.47 V) or 5 V (4.75–5.25 V) analog supply (VDD). The digital I/O supply (OVDD) is independently configurable from 1.71 V to 2.63 V, allowing compatibility with 1.8 V or 2.5 V FPGA/ASIC logic families regardless of analog rail choice.
