Product details
Overview
LTC2325CUKG-16#TRPBF from Analog Devices (formerly Linear Technology) is a quad, 16-bit, 5 Msps/channel simultaneous-sampling successive approximation register (SAR) ADC with true differential inputs, integrated 4.096 V reference, and CMOS/LVDS serial interface. It delivers ±2 LSB INL typical, 82 dB SNR at 2.2 MHz input, and operates from single 3.3 V or 5 V supply - ideal for high-fidelity data acquisition in motor control and optical networking.
For engineers reviewing the LTC2325CUKG-16#TRPBF datasheet, LTC2325CUKG-16#TRPBF pinout, LTC2325CUKG-16#TRPBF application, or LTC2325CUKG-16#TRPBF equivalent, key selection factors include guaranteed 16-bit no-missing-codes operation, 52-pin QFN package with exposed thermal pad, simultaneous sampling across four channels, internal reference accuracy (20 ppm/°C max), and support for both CMOS and LVDS I/O modes with SDR/DDR flexibility.
Technical Context
The LTC2325CUKG-16#TRPBF implements four independent SAR ADC cores sharing a common reference architecture and synchronized CNV control, enabling true simultaneous sampling with <500 ps aperture delay matching. Its internal 4.096 V reference buffer (REFBUFEN-controllable) supports unipolar/bipolar configurations and can be overdriven by external references between 1.25 V and 5 V.
Digital interface flexibility includes selectable CMOS or LVDS signaling (via CMOS/LVDS pin), SDR/DDR mode (via SDR/DDR pin), and skew-matched CLKOUT output for FPGA latch timing. Power management features include nap mode (6.4 mA IVDD) and sleep mode (90 µW total), with full operation specified from 0°C to 70°C (C-grade).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, guaranteed no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Sampling Rate | 5 Msps per channel, simultaneous - enables real-time capture of four synchronized analog signals at up to 5 million samples/sec each. |
| SNR | 82 dB typical at fIN = 2.2 MHz - supports >13.3 effective bits for high-fidelity signal reconstruction in demanding applications. |
| INL | ±2 LSB typical - minimizes integral nonlinearity error critical for closed-loop control accuracy and calibration stability. |
| Reference | Internal 4.096 V ±0.5%, 20 ppm/°C max drift - eliminates need for external reference and reduces BOM count while maintaining temperature stability. |
| Power Dissipation | 40 mW per channel at 5 Msps (5 V supply) - balances high-speed performance with thermal manageability in dense PCB layouts. |
| Package | 52-pin QFN (7 mm × 8 mm), exposed pad - provides low-inductance ground path and efficient thermal dissipation for continuous high-throughput operation. |
Pinout & Package
Package: 52-lead plastic QFN (7 mm × 8 mm), exposed thermal pad (Pin 53) soldered to PCB ground plane for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– to AIN4+ / AIN4– (Pins 1–2, 4–5, 10–11, 13–14) | Four differential analog inputs | Support ±4.096 V full-scale range with wide common-mode range (0 V to VDD); enable true simultaneous sampling of four independent signals. |
| REFOUT1–REFOUT4 (Pins 6, 9, 22, 45) | Per-channel reference buffer outputs | Each drives dedicated ADC core; configurable via REFBUFEN to use internal 4.096 V or external reference (1.25–5 V). |
| SDO1–SDO4 / SDOA±–SDOD± (Pins 27, 29, 35, 39 and 28, 30, 36, 40) | Serial data outputs (CMOS or LVDS) | CMOS mode: single-ended SDOx; LVDS mode: differential SDOx±; supports SDR (16 clocks) or DDR (8 clocks) readout per 16-bit sample. |
| SCK / SCK± (Pin 41 / Pins 41–42) | Serial clock input | Accepts CMOS or differential LVDS clock; timing determines data capture edge (falling-edge SDR or dual-edge DDR). |
| CNV (Pin 24) | Convert initiation input | High = acquisition phase; falling edge initiates conversion and triggers serial data output - enables precise system-level synchronization. |
| CLKOUT / CLKOUT± (Pin 33 / Pins 33–34) | Skew-matched output clock | Echoes SCK with minimal delay; used to latch SDO data at FPGA receiver - eliminates clock-data skew issues in high-speed interfaces. |
| CMOS/LVDS (Pin 25) | I/O interface mode select | GND = CMOS; OVDD = LVDS; floating = low-power LVDS - allows hardware-selectable interface standard without redesign. |
| SDR/DDR (Pin 23) | Data rate mode select | GND = SDR (16 SCK edges per 16-bit word); OVDD = DDR (8 SCK edges) - doubles effective throughput without increasing clock frequency. |
| REFBUFEN (Pin 43) | Reference buffer enable | Tie to VDD for internal reference; ground to disable buffers and use external reference - provides flexible reference architecture. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 16-bit simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7606C-16 | 8-channel, parallel/serial interface; 200 kSPS per channel; internal 2.5 V reference; no LVDS option | Better suited for lower-speed, higher-channel-count industrial PLCs where parallel bus simplifies FPGA interfacing | Select AD7606C-16 when channel count >4 and speed ≤200 kSPS suffices; avoid when LVDS, 5 Msps/ch, or simultaneous 4-channel timing is required. |
| ADS8684 | 4-channel, pseudo-simultaneous sampling (sequential core activation); SPI-only CMOS interface; 500 kSPS per channel; integrated PGA | Targeted at programmable logic controller (PLC) analog input modules needing on-chip gain scaling and lower power | Select ADS8684 when input signal conditioning (PGA) and lower throughput (≤500 kSPS) are acceptable; not suitable for true simultaneous acquisition or >1 Msps applications. |

FAQ
What is the operating temperature range for the LTC2325CUKG-16#TRPBF?
The LTC2325CUKG-16#TRPBF is rated for 0°C to 70°C (Commercial grade). This is confirmed by the "C" suffix in the part number and the order information table specifying "0°C to 70°C" for LTC2325CUKG-16#TRPBF. The device achieves full performance specifications-including ±2 LSB INL, 82 dB SNR, and 5 Msps throughput-across this entire range.
Does the LTC2325CUKG-16#TRPBF require an external reference?
No, the LTC2325CUKG-16#TRPBF does not require an external reference. It integrates a low-drift 4.096 V temperature-compensated reference with 20 ppm/°C max drift. REFBUFEN (Pin 43) must be tied to VDD to enable the internal reference buffers (REFOUT1–REFOUT4). External references (1.25 V to 5 V) are optional and only needed when higher precision or different voltage levels are required.
How many pins does the LTC2325CUKG-16#TRPBF have, and what is its package type?
The LTC2325CUKG-16#TRPBF uses a 52-lead plastic QFN package measuring 7 mm × 8 mm with an exposed thermal pad (Pin 53). This is explicitly stated in the "ORDER INFORMATION" section and "PIN CONFIGURATION" diagram. The exposed pad must be soldered to the PCB ground plane for proper thermal and electrical performance.
Can the LTC2325CUKG-16#TRPBF operate with both CMOS and LVDS digital interfaces?
Yes, the LTC2325CUKG-16#TRPBF supports both CMOS and LVDS digital interfaces. The CMOS/LVDS pin (Pin 25) selects the mode: grounded for CMOS, tied to OVDD for LVDS, or left floating for low-power LVDS. Each of the four SDO outputs and SCK/CLKOUT signals adapt accordingly - single-ended for CMOS, differential for LVDS - with appropriate termination requirements.
What is the maximum sampling rate per channel for the LTC2325CUKG-16#TRPBF?
The maximum sampling rate per channel for the LTC2325CUKG-16#TRPBF is 5 Msps (5 million samples per second), with simultaneous sampling across all four channels. This is guaranteed across the full operating temperature range and is confirmed in the "ELECTRICAL CHARACTERISTICS" table under fSMPL, as well as in the "FEATURES" and "TYPICAL APPLICATION" sections.
