It operates from single 3.3 V or 5 V supply and supports CMOS or LVDS serial interface - ideal for high-speed data acquisition in multiphase motor control and optical networking.

For engineers reviewing the LTC2324CUKG-16#TRPBF datasheet, LTC2324CUKG-16#TRPBF pinout, LTC2324CUKG-16#TRPBF application, or LTC2324CUKG-16#TRPBF equivalent, key selection considerations include simultaneous 4-channel sampling, internal reference accuracy (20 ppm/°C max), LVDS/CMOS I/O flexibility, low-latency 220 ns conversion time, and operation across 0°C to 70°C industrial temperature range.

Technical Context

The LTC2324CUKG-16#TRPBF implements four independent successive approximation register (SAR) ADC cores with synchronized sample-and-hold circuits, enabling true simultaneous sampling across all channels. Its architecture supports both internal buffered reference (4.096 V or 2.048 V) and external reference configurations via REFBUFEN control.

Digital interface flexibility includes selectable CMOS or LVDS I/O modes (via CMOS/LVDS pin), SDR/DDR clocking (via SDR/DDR pin), and skew-matched CLKOUT for FPGA synchronization. Power management features include nap mode (5.3 mA) and sleep mode (20 µA), with total power dissipation of 102 mW at 3.3 V / 2 Msps per channel.

FAQ

What is the maximum sampling rate per channel for the LTC2324CUKG-16#TRPBF?

The LTC2324CUKG-16#TRPBF achieves a guaranteed 2 Msps per channel across all four simultaneously sampled inputs. This rate is supported in both CMOS and LVDS I/O modes, with conversion time fixed at 220 ns and no pipeline latency - enabling deterministic real-time signal processing in applications like motor control and spectrum analysis.

Does the LTC2324CUKG-16#TRPBF include an internal voltage reference?

Yes, the LTC2324CUKG-16#TRPBF integrates a low-drift, temperature-compensated reference that outputs either 2.048 V or 4.096 V (selectable via REFBUFEN and external decoupling). The reference exhibits ≤20 ppm/°C max drift and 0.3 mV/V line regulation, eliminating the need for external reference components in most precision applications.

Can the LTC2324CUKG-16#TRPBF operate with both CMOS and LVDS digital interfaces?

Yes, the LTC2324CUKG-16#TRPBF supports both CMOS and LVDS serial I/O modes, selected by the CMOS/LVDS pin (grounded for CMOS, tied to OVDD for LVDS, or floated for low-power LVDS). Each mode supports SDR or DDR clocking, allowing designers to optimize for noise immunity, power, or interface compatibility without changing the LTC2324CUKG-16#TRPBF hardware.

What is the operating temperature range for the LTC2324CUKG-16#TRPBF?

The LTC2324CUKG-16#TRPBF is specified for operation from 0°C to 70°C (Commercial grade, denoted by 'C' in the part number). Electrical characteristics including INL (±2 LSB typ), SNR (82 dB typ), and reference drift (20 ppm/°C max) are guaranteed across this full range, ensuring reliable performance in industrial control panels and test equipment.

How does the simultaneous sampling architecture of the LTC2324CUKG-16#TRPBF benefit system design?

The LTC2324CUKG-16#TRPBF uses four independent sample-and-hold circuits triggered by a single CNV signal, ensuring true simultaneous acquisition across all channels with <500 ps aperture delay matching. This eliminates inter-channel phase skew - critical for vector measurements in motor control, coherent optical detection, and multi-sensor condition monitoring where timing alignment directly impacts algorithm accuracy.
