Analog Devices Inc. LTC2324HUKG-16#TRPBF

Overview

LTC2324HUKG-16#TRPBF from Analog Devices is a quad, 16-bit, 2 Msps/channel simultaneous-sampling SAR ADC with differential inputs, ±4.096 V input range, 82 dB SNR (typ), ±2 LSB INL (typ), and guaranteed operation from –40°C to 125°C. It integrates four independent 16-bit ADC cores with individual reference buffers and supports high-speed data acquisition in multiphase motor control and optical networking systems.

For engineers reviewing the LTC2324HUKG-16#TRPBF datasheet, LTC2324HUKG-16#TRPBF pinout, LTC2324HUKG-16#TRPBF application, or LTC2324HUKG-16#TRPBF equivalent, key selection considerations include simultaneous sampling accuracy across all four channels, LVDS/CMOS serial interface flexibility, internal 4.096 V reference stability over temperature, and thermal robustness for industrial and automotive-grade signal conditioning.

Technical Context

The LTC2324HUKG-16#TRPBF implements four independent successive approximation register (SAR) ADCs sharing a common CNV timing control, enabling true simultaneous sampling with <500 ps aperture delay matching. Each channel features dedicated REFOUTx pins and supports either internal 4.096 V reference (20 ppm/°C max drift) or external reference configuration via REFBUFEN.

It operates from single 3.3 V or 5 V analog supply (VDD) and 1.71–2.63 V digital I/O supply (OVDD), with configurable CMOS/LVDS serial interface supporting SDR or DDR modes. Power dissipation is 162 mW at 5 V / 2 Msps per channel, dropping to 30 µW in sleep mode.

FAQ

What is the maximum sampling rate per channel for the LTC2324HUKG-16#TRPBF?

The LTC2324HUKG-16#TRPBF achieves a maximum sampling rate of 2 Msps per channel, with guaranteed simultaneous sampling across all four channels. This is supported by its 220 ns conversion time and 0.5 µs minimum cycle time, enabling real-time capture of fast transients in industrial and communications systems. The LTC2324HUKG-16#TRPBF maintains this rate across its full –40°C to +125°C operating range.

Does the LTC2324HUKG-16#TRPBF include an internal voltage reference?

Yes, the LTC2324HUKG-16#TRPBF integrates a low-drift, temperature-compensated internal reference delivering 4.096 V (or 2.048 V) with a maximum drift of 20 ppm/°C. The reference is available on four dedicated REFOUT pins (REFOUT1–4), one per ADC channel, and can be disabled via the REFBUFEN pin to accommodate external references from 1.25 V to 5 V.

Can the LTC2324HUKG-16#TRPBF operate with both CMOS and LVDS digital interfaces?

Yes, the LTC2324HUKG-16#TRPBF supports both CMOS and LVDS serial interfaces, selected by the CMOS/LVDS pin. In CMOS mode (pin grounded), it drives 1.8 V or 2.5 V logic levels; in LVDS mode (pin tied to OVDD), it delivers differential outputs compliant with ANSI TIA/EIA-644-A. Low-power LVDS is enabled by floating the CMOS/LVDS pin.

What is the guaranteed operating temperature range for the LTC2324HUKG-16#TRPBF?

The LTC2324HUKG-16#TRPBF is rated for operation from –40°C to +125°C, corresponding to the "H" grade in the LTC2324 family. This extended temperature range is fully characterized and guaranteed for all electrical specifications, including INL, SNR, and reference stability, making it suitable for under-hood automotive, downhole, and industrial edge applications.

How does the LTC2324HUKG-16#TRPBF handle simultaneous sampling across its four channels?

The LTC2324HUKG-16#TRPBF uses a shared CNV input to initiate simultaneous track-and-hold across all four SAR ADCs, achieving aperture delay matching of ≤500 ps. Its functional block diagram confirms independent sampling capacitors and conversion paths per channel, ensuring phase-coherent acquisition without software synchronization overhead. This architecture is essential for vector control and power quality analysis.
