Product details
Overview
LTC2324IUKG-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 integrated 2.048 V / 4.096 V temperature-compensated reference. It operates from single 3.3 V or 5 V supply and supports CMOS/LVDS serial interface - ideal for high-speed data acquisition in multiphase motor control and optical networking.
For engineers reviewing the LTC2324IUKG-16#TRPBF datasheet, LTC2324IUKG-16#TRPBF pinout, LTC2324IUKG-16#TRPBF application, or LTC2324IUKG-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, simultaneous sampling across four channels, low-power nap/sleep modes (26 μW), LVDS/CMOS I/O flexibility, and operation over –40°C to +85°C industrial temperature range.
Technical Context
The LTC2324IUKG-16#TRPBF implements four independent 16-bit successive approximation register (SAR) ADC cores with true differential input stages and matched sample-and-hold circuits enabling precise simultaneous sampling. Its internal reference buffer delivers stable 4.096 V (or 2.048 V) outputs per channel with ≤20 ppm/°C drift.
It supports dual-mode serial interface: CMOS (1.8 V–2.5 V I/O) or LVDS (2.5 V OVDD), configurable via CMOS/LVDS and SDR/DDR pins. Timing is synchronized by CNV edge-triggered conversion and skew-matched CLKOUT output, eliminating inter-channel latency and ensuring deterministic readout at up to 2 Msps per channel.

Pinout & Package
Package: 52-lead (7 mm × 8 mm) plastic QFN with exposed thermal pad (Pin 53 = GND). RoHS-compliant, lead-free, tape-and-reel packaging (#TRPBF).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– to AIN4+ / AIN4– (Pins 1–2, 4–5, 10–11, 13–14) | Differential analog inputs (x4 channels) | Accept ±4.096 V differential swing with wide common-mode range (0 V to VDD); enable true simultaneous sampling without inter-channel skew. |
| REFOUT1–REFOUT4 (Pins 6, 9, 22, 45) | Per-channel reference buffer outputs | Provide isolated 4.096 V references for each ADC core; disable via REFBUFEN to support external reference sharing. |
| SDO1–SDO4 / SDOA±–SDOD± (Pins 27, 29, 35, 39 & 28, 30, 36, 40) | Serial data outputs (CMOS or LVDS) | Four independent high-speed data lanes - LVDS mode reduces EMI and supports >100 MHz clock rates; CMOS mode simplifies FPGA interfacing at 1.8 V/2.5 V. |
| CMOS/LVDS (Pin 25), SDR/DDR (Pin 23) | I/O interface mode configuration | Hardware-selectable interface standard and data rate - no firmware overhead; LVDS DDR achieves 2× throughput efficiency vs CMOS SDR. |
| CNV (Pin 24) | Edge-triggered convert command | Rising edge initiates acquisition; falling edge triggers conversion and data output - enables precise timing control and deterministic latency. |
| CLKOUT / CLKOUT± (Pins 33–34) | Skew-matched output clock | Provides receiver-synchronized latch clock with minimal delay variation (<500 ps matching) - essential for multi-channel time-aligned capture in FPGAs. |
Key Features
| Feature | Design Value |
|---|---|
| Quad simultaneous sampling | Four matched SAR cores share one CNV edge - eliminates phase skew between channels for accurate multiphase waveform analysis. |
| Configurable I/O interface | Single hardware pin (CMOS/LVDS) selects between low-power CMOS (1.8 V/2.5 V) or noise-immune LVDS (2.5 V) signaling - adapts to host processor capability without redesign. |
| Per-channel reference buffers | Four independent 4.096 V reference outputs (REFOUT1–4) reduce crosstalk and maintain channel isolation - critical for mixed-signal systems with varying source impedances. |
| Low-latency power states | Nap mode (5.3 mA) and sleep mode (20 μA) respond within microseconds - enables burst-mode acquisition while minimizing average power in battery-powered DAQ systems. |
| Industrial temperature grade | Specified from –40°C to +85°C with full performance - supports deployment in factory automation, motor drives, and outdoor telecom infrastructure without thermal margining. |

FAQ
What is the maximum sampling rate per channel for the LTC2324IUKG-16#TRPBF?
The LTC2324IUKG-16#TRPBF achieves a maximum sampling rate of 2 Msps per channel across all four simultaneously sampled inputs. This rate is maintained with full 16-bit resolution, no missing codes, and specified AC performance (82 dB SNR, ±2 LSB INL) over the full –40°C to +85°C operating range. The device sustains this throughput in both CMOS and LVDS I/O modes.
Does the LTC2324IUKG-16#TRPBF require an external reference voltage?
No, the LTC2324IUKG-16#TRPBF integrates a low-drift (≤20 ppm/°C) 4.096 V (or 2.048 V) temperature-compensated reference buffer with four independent outputs (REFOUT1–REFOUT4). External reference is optional: grounding REFBUFEN allows overdriving any REFOUT pin with an external 1.25 V–5 V source, enabling system-level reference sharing or enhanced accuracy.
How does the LTC2324IUKG-16#TRPBF support simultaneous sampling across four channels?
The LTC2324IUKG-16#TRPBF uses four fully independent SAR ADC cores, each with its own matched sample-and-hold circuit, all triggered by a single CNV edge. This architecture guarantees true simultaneous sampling with <500 ps inter-channel aperture delay matching - critical for phase-coherent measurements in motor control and communications systems.
What digital interface options does the LTC2324IUKG-16#TRPBF support?
The LTC2324IUKG-16#TRPBF supports two hardware-configurable digital interfaces: CMOS (1.8 V or 2.5 V I/O levels) and LVDS (2.5 V OVDD). Interface mode is selected via the CMOS/LVDS pin; data rate (SDR or DDR) is set by SDR/DDR pin. LVDS mode provides superior noise immunity and supports >100 MHz clock rates, while CMOS simplifies FPGA/microcontroller integration.
What power-saving modes are available on the LTC2324IUKG-16#TRPBF?
The LTC2324IUKG-16#TRPBF offers two low-power states: Nap mode (5.3 mA total supply current) entered after conversion completes, and Sleep mode (20 μA total supply current) for extended idle periods. Both modes retain register settings and wake instantly upon CNV assertion - enabling energy-efficient burst-mode acquisition in portable or thermally constrained systems.
