Product details
Overview
LTC2324IUKG-14#PBF from Analog Devices is a quad, 14-bit + sign successive approximation register (SAR) analog-to-digital converter with simultaneous sampling across all four channels at 2 Msps per channel, differential inputs with ±4.096 V full-scale range, 81 dB SNR at 500 kHz input, and integrated 4.096 V temperature-compensated reference. It operates from single 3.3 V or 5 V supply and supports CMOS or LVDS serial interface for high-speed data acquisition in motor control and optical networking.
For engineers reviewing the LTC2324IUKG-14#PBF datasheet, LTC2324IUKG-14#PBF pinout, LTC2324IUKG-14#PBF application, or LTC2324IUKG-14#PBF equivalent, key selection criteria include guaranteed 14-bit no-missing-codes performance, simultaneous sampling timing matching (<500 ps aperture delay matching), internal reference stability (20 ppm/°C max), low power dissipation (40 mW/ch typical), and operation over –40°C to +85°C industrial temperature range.
Technical Context
The LTC2324IUKG-14#PBF implements four independent SAR ADC cores sharing a common reference architecture with individually buffered REFOUT1–4 outputs. Each core features true differential input stages with 102 dB common-mode rejection at 500 kHz and 55 MHz –3 dB input bandwidth.
Its digital interface supports configurable I/O modes (CMOS/LVDS/low-power LVDS) and data transfer protocols (SDR/DDR), with dedicated SDOx pins per channel and skew-matched CLKOUT for FPGA synchronization. Conversion is initiated by CNV edge, with zero-latency readout and 220 ns conversion time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: 52-lead (7 mm × 8 mm) plastic QFN with exposed thermal pad (Pin 53 = GND). Requires soldering of exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– to AIN4+ / AIN4– (Pins 1–2, 4–5, 10–11, 13–14) | Differential analog inputs | Four independent true-differential pairs accepting ±4.096 V full-scale range; support bipolar/unipolar/arbitrary input configurations without external level-shifting. |
| REFOUT1–4 (Pins 6, 9, 22, 45) | Per-channel reference buffer outputs | Individually decoupled 4.096 V reference sources-enables channel-specific gain calibration or isolated reference domains in multi-sensor systems. |

FAQ
What is the operating temperature range for the LTC2324IUKG-14#PBF?
The LTC2324IUKG-14#PBF is rated for operation from –40°C to +85°C, qualifying it for industrial environments including factory automation, outdoor telecom equipment, and motor drive enclosures. This grade ('I') is distinct from the 'C' (0°C to 70°C) and 'H' (–40°C to 125°C) variants. The datasheet specifies all electrical characteristics-including INL, SNR, and reference drift-over this full range.
Does the LTC2324IUKG-14#PBF require an external reference?
No, the LTC2324IUKG-14#PBF includes an onboard low-drift 4.096 V temperature-compensated reference with 20 ppm/°C maximum drift, eliminating the need for external reference components in most applications. REFBUFEN (Pin 43) can disable internal buffers if an external reference is preferred-allowing use of a system-level master reference for improved channel-to-channel coherence.
How does the simultaneous sampling architecture of the LTC2324IUKG-14#PBF benefit multiphase motor control?
The LTC2324IUKG-14#PBF achieves <500 ps aperture delay matching between its four ADC channels, ensuring that current and voltage samples across all three motor phases (and neutral/DC bus) are captured at precisely the same instant. This temporal coherence is essential for accurate field-oriented control calculations, minimizing torque ripple and improving dynamic response in servo and inverter systems.
Can the LTC2324IUKG-14#PBF interface directly with an FPGA using LVDS?
Yes, the LTC2324IUKG-14#PBF supports LVDS mode via the CMOS/LVDS pin (Pin 25). In LVDS mode, it provides differential SDOA–D± and CLKOUT± outputs with 100 Ω termination requirements, delivering deterministic timing with <1 ps RMS aperture jitter. The skew-matched CLKOUT ensures reliable data capture in Xilinx or Intel FPGAs without additional clock deskew circuitry.
What power-saving modes does the LTC2324IUKG-14#PBF support?
The LTC2324IUKG-14#PBF offers two low-power states: Nap mode draws 6.4 mA total (IVDD), reducing power during idle intervals between conversions; Sleep mode draws only 90 µA (IVDD + IOVDD), ideal for battery-operated DAQ nodes. Both modes retain register settings and reference state, enabling fast wake-up (<50 ms REFOUT stabilization) without reconfiguration overhead.
