Analog Devices Inc. LTC2324IUKG-12#TRPBF

Overview

LTC2324IUKG-12#TRPBF from Analog Devices is a quad, 12-bit + sign successive approximation register (SAR) analog-to-digital converter with simultaneous sampling across four differential input channels, 2 Msps per channel throughput, ±0.5 LSB typical INL, 78 dB SNR at 500 kHz, and operation over –40°C to +85°C - ideal for high-speed data acquisition in multiphase motor control and optical networking systems.

For engineers reviewing the LTC2324IUKG-12#TRPBF datasheet, LTC2324IUKG-12#TRPBF pinout, LTC2324IUKG-12#TRPBF application, or LTC2324IUKG-12#TRPBF equivalent, this page delivers verified electrical specs, package mapping, I/O mode configuration (CMOS/LVDS), reference buffer enable logic, and real-world timing behavior for FPGA- or ASIC-based high-fidelity signal capture.

Technical Context

The LTC2324IUKG-12#TRPBF implements four independent SAR ADC cores sharing a common internal 2.048 V / 4.096 V temperature-compensated reference, each with true differential inputs (±REFOUTx range), wide common-mode range (0 V to VDD), and 102 dB CMRR at 500 kHz. It supports both SDR and DDR serial readout via configurable CMOS or LVDS I/O interfaces.

Its architecture enables zero-latency conversion with 220 ns conversion time, aperture jitter of 1 ps RMS, and <500 ps aperture delay matching across all four channels - critical for phase-coherent multi-channel acquisition in communications and instrumentation applications.

FAQ

What is the operating temperature range of the LTC2324IUKG-12#TRPBF?

The LTC2324IUKG-12#TRPBF is rated for operation from –40°C to +85°C (Industrial grade). This is confirmed by the "I" suffix in the part number and explicitly stated in the Absolute Maximum Ratings table. The device maintains full 12-bit performance, including ±0.5 LSB INL and 78 dB SNR, across this entire range.

Does the LTC2324IUKG-12#TRPBF include an internal voltage reference?

Yes, the LTC2324IUKG-12#TRPBF integrates a low-drift, temperature-compensated reference that outputs either 2.048 V or 4.096 V, selectable via external resistor divider on REF pin. The REFBUFEN pin (Pin 43) controls whether internal buffers drive REFOUT1–4; grounding REFBUFEN disables them for external reference use.

How does the CNV pin function in the LTC2324IUKG-12#TRPBF?

The CNV pin (Pin 24) is the master convert trigger. Its rising edge initiates the sampling aperture; its falling edge triggers conversion start and enables serial data output on SDOx pins. This edge-controlled timing ensures deterministic, low-jitter synchronization across all four channels in the LTC2324IUKG-12#TRPBF.

Can the LTC2324IUKG-12#TRPBF operate with both CMOS and LVDS digital interfaces?

Yes - the LTC2324IUKG-12#TRPBF supports CMOS, LVDS, and low-power LVDS I/O modes. The CMOS/LVDS pin (Pin 25) selects mode: grounded for CMOS, tied to OVDD for LVDS, or floating for low-power LVDS. Pin functions (e.g., SDO1 vs. SDOA±) and timing specs differ accordingly, as detailed in the Pin Functions section.

What is the significance of the SDR/DDR pin on the LTC2324IUKG-12#TRPBF?

The SDR/DDR pin (Pin 23) configures serial data transfer rate. When tied to GND, the LTC2324IUKG-12#TRPBF operates in Single Data Rate mode (13 SCK edges per 13-bit word). When tied to OVDD, it enables Double Data Rate mode (13 SCK edges, two bits per edge), effectively doubling data throughput without increasing SCK frequency - reducing EMI and timing margin pressure.
