Analog Devices Inc. LTC2320IUKG-12#PBF

Overview

LTC2320IUKG-12#PBF from Analog Devices is an octal, 12-bit + sign successive approximation register (SAR) analog-to-digital converter with simultaneous sampling across all eight differential input channels. It delivers 1.5 Msps per channel throughput, 77 dB SNR at 500 kHz input, ±0.25 LSB typical INL, and operates from a single 3.3 V or 5 V supply - enabling high-fidelity data acquisition in multiphase motor control and optical networking systems.

For engineers reviewing the LTC2320IUKG-12#PBF datasheet, LTC2320IUKG-12#PBF pinout, LTC2320IUKG-12#PBF application, or LTC2320IUKG-12#PBF equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with documented functional and application-level distinctions.

Technical Context

The LTC2320IUKG-12#PBF integrates eight independent SAR ADC cores with synchronized sample-and-hold, supporting true simultaneous sampling across all channels without inter-channel skew. Its internal temperature-compensated reference offers selectable 2.048 V or 4.096 V outputs with ≤20 ppm/°C drift, and supports both CMOS and LVDS serial interfaces with SDR/DDR modes.

It features 8 VP-P differential inputs with 0–VDD common-mode range and 102 dB CMRR at 500 kHz, enabling direct interfacing to wide-dynamic-range sensors and isolated signal chains. Power management includes nap mode (6.2 mA) and sleep mode (20 µA), with total power dissipation of 208 mW at 5 V/1.5 Msps.

FAQ

What is the maximum sampling frequency per channel for the LTC2320IUKG-12#PBF?

The LTC2320IUKG-12#PBF achieves a guaranteed 1.5 Msps per channel throughput rate across all eight simultaneously sampled channels. This is supported by its internal architecture - including synchronized sample-and-hold circuits and optimized SAR conversion timing - and is specified under full operating conditions (–40°C to +85°C, VDD = 5 V, fSMPL = 1.5 MHz). The device maintains no missing codes and ±0.25 LSB INL at this rate.

Does the LTC2320IUKG-12#PBF include an internal voltage reference?

Yes, the LTC2320IUKG-12#PBF integrates four independent, low-drift voltage reference buffers delivering either 2.048 V or 4.096 V (depending on VDD), with a maximum temperature coefficient of 20 ppm/°C. These buffers drive REFOUT1–4 pins and can be disabled via the REFBUFEN pin to accommodate external references - giving designers flexibility in system-level reference architecture without adding discrete ICs.

Can the LTC2320IUKG-12#PBF operate with both CMOS and LVDS digital interfaces?

Yes, the LTC2320IUKG-12#PBF supports both CMOS and LVDS serial I/O through the CMOS/LVDS pin: grounding it selects CMOS mode (1.8 V/2.5 V logic), tying it to OVDD enables standard LVDS, and floating it activates low-power LVDS. Each mode supports Single Data Rate (SDR) and Double Data Rate (DDR) configurations via the SDR/DDR pin - allowing seamless integration with diverse host processors and FPGAs.

What is the operating temperature range of the LTC2320IUKG-12#PBF?

The LTC2320IUKG-12#PBF is rated for industrial operation from –40°C to +85°C, as indicated by the "I" grade in its part number. This rating is fully guaranteed across all electrical specifications - including 77 dB SNR, ±0.25 LSB INL, and 1.5 Msps throughput - making it suitable for deployment in motor drives, outdoor telecom equipment, and factory automation systems exposed to wide ambient variations.

How many analog input channels does the LTC2320IUKG-12#PBF support, and what is their configuration?

The LTC2320IUKG-12#PBF supports eight fully differential analog input channels (AIN1+/- through AIN8+/-), arranged in four independent reference groups (REFOUT1–4). Each group of two channels shares a dedicated reference buffer output, enabling flexible scaling - for example, using REFOUT1 for high-gain current sensing and REFOUT3 for low-gain voltage monitoring - all within a single 52-lead QFN package.
