Product details
Overview
LTC2323HUFD-14#TRPBF from Analog Devices is a dual, 14-bit + sign successive approximation register (SAR) analog-to-digital converter with differential inputs, 5 Msps per channel throughput, ±1 LSB typical INL, 80 dB SNR at 2.2 MHz, 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 or LVDS serial interface - ideal for high-speed data acquisition in automotive and industrial control systems.
For engineers reviewing the LTC2323HUFD-14#TRPBF datasheet, LTC2323HUFD-14#TRPBF pinout, LTC2323HUFD-14#TRPBF application, or LTC2323HUFD-14#TRPBF equivalent, key selection criteria include guaranteed 14-bit no-missing-codes operation over –40°C to +125°C, 1-cycle latency, 8 VP-P differential input range with wide common-mode support, and low-power nap/sleep modes down to 5 µW.
Technical Context
The LTC2323HUFD-14#TRPBF implements two independent SAR ADC cores with fully differential sample-and-hold front-ends, each supporting 15-bit resolution (14-bit + sign) across ±REFOUT full-scale span. Its internal reference buffers deliver 4.096 V or 2.048 V with ≤20 ppm/°C drift and are disableable for external reference use.
Timing is synchronized via CNV falling edge; conversion completes in 171.5 ns with one-cycle latency. Serial output uses SCK-driven MSB-first transfer on SDO1/SDO2, with skew-matched CLKOUT for receiver synchronization - configurable for CMOS (1.8 V–2.5 V I/O) or LVDS (100 Ω differential termination) operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit + sign (15-bit two's complement output), enabling bipolar signal digitization without external level-shifting. |
| Sampling Rate | 5 Msps per channel - supports real-time capture of signals up to 10 MHz bandwidth (–3 dB input linear bandwidth). |
| INL | ±1 LSB typical - ensures accurate amplitude fidelity in closed-loop motor control and precision instrumentation. |
| SNR | 80 dB typical at fIN = 2.2 MHz - delivers >13 effective bits for high-fidelity signal analysis in optical networking. |
| Reference | Internal 4.096 V / 2.048 V, low-drift (≤20 ppm/°C), temperature-compensated - eliminates need for external reference in space-constrained designs. |
| Power | 38 mW per channel at 5 Msps (5 V), 5 µW in sleep mode - enables energy-efficient operation in remote sensing nodes. |
| Temperature Range | –40°C to +125°C (H-grade) - qualified for under-hood automotive and harsh industrial environments. |
Pinout & Package
Package: 28-lead (4 mm × 5 mm) plastic QFN (UFD) with exposed pad (Pin 29) soldered to PCB ground plane. Thermal resistance θJA = 43°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 8) | Analog power supply | Single 3.3 V or 5 V supply; requires local 10 µF + 0.1 µF bypassing - powers ADC core and reference buffers. |
| AIN1+, AIN1– (Pins 7, 6); AIN2+, AIN2– (Pins 2, 3) | Differential analog inputs | Support fully differential, pseudo-differential bipolar/unipolar modes without configuration; 8 VP-P full-scale range with 85 dB CMRR at 2.2 MHz. |
| CNV (Pin 9) | Conversion start trigger | Falling-edge initiated; requires low-jitter source - defines precise sampling instant for time-critical control loops. |
| REFOUT1/REFOUT2 (Pins 12, 26) | Reference buffer outputs | Nominally 4.096 V (or 2.048 V); decoupled with 10 µF + 0.1 µF capacitors - provides stable, low-noise reference for both channels. |
| SDO1+/SDO1–, SDO2+/SDO2– (Pins 15–16, 19–20) | Serial data outputs | MSB-first, 15-bit two's complement; LVDS mode requires 100 Ω differential termination at FPGA/CPLD - enables noise-immune high-speed digital interface. |
| SCK+, SCK– (Pins 21–22) | Serial clock input | Drives data shift; LVDS mode requires differential 100 Ω termination - supports up to 105 MHz SCK for minimal readout latency. |
| CLKOUT+, CLKOUT– (Pins 17–18) | Skew-matched output clock | Phase-aligned with SDO edges - eliminates setup/hold timing margin concerns at receiver (e.g., FPGA input registers). |
| CMOS/LVDS (Pin 25) | I/O interface mode select | GND = CMOS; OVDD = LVDS; floating = low-power LVDS - configures drive strength and termination requirements without external logic. |
Key Features

FAQ
What is the maximum sampling rate supported by the LTC2323HUFD-14#TRPBF?
The LTC2323HUFD-14#TRPBF supports a maximum sampling rate of 5 Msps per channel, with guaranteed timing performance across its full –40°C to +125°C operating temperature range. This rate is achieved using the internal CNV-triggered conversion cycle and is compatible with both CMOS and LVDS serial interface modes. The device maintains 1-cycle latency and 171.5 ns conversion time at this rate, enabling deterministic real-time acquisition in control applications.
Does the LTC2323HUFD-14#TRPBF require an external reference voltage?
No, the LTC2323HUFD-14#TRPBF includes an onboard low-drift (≤20 ppm/°C) temperature-compensated reference that outputs either 2.048 V or 4.096 V on REFOUT1 and REFOUT2 pins. The internal reference can be disabled by grounding REFINT (Pin 28) to allow use of an external reference between 1.25 V and VDD. For most applications, especially those requiring minimal BOM count and layout area, the internal reference is fully sufficient and characterized over temperature.
How does the LTC2323HUFD-14#TRPBF handle pseudo-differential and fully differential input configurations?
The LTC2323HUFD-14#TRPBF supports fully differential, pseudo-differential bipolar, and pseudo-differential unipolar inputs without hardware configuration. In fully differential mode, AIN1+/AIN1– and AIN2+/AIN2– accept complementary signals spanning ±REFOUT. In pseudo-differential mode, one input is held fixed (e.g., at mid-supply or ground) while the other carries the signal - automatically generating correct two's complement codes. The device's wide 0 V to VDD common-mode range ensures compatibility with diverse front-end topologies.
What are the power consumption characteristics of the LTC2323HUFD-14#TRPBF in different operating modes?
At 5 Msps with 5 V supply and CMOS interface, the LTC2323HUFD-14#TRPBF consumes 38 mW per channel (76 mW total). In nap mode (conversion complete), power drops to 15 mW; in sleep mode, it falls to just 5 µW. These values scale with supply voltage and interface choice - e.g., LVDS mode increases OVDD current but maintains low analog supply draw. All modes are specified over –40°C to +125°C, making the part suitable for energy-conscious embedded systems with variable duty cycles.
Can the LTC2323HUFD-14#TRPBF operate reliably in automotive under-hood environments?
Yes, the LTC2323HUFD-14#TRPBF is rated for –40°C to +125°C operation (H-grade) and is qualified for automotive under-hood use. Its guaranteed 14-bit no-missing-codes performance, ±1 LSB INL, and 80 dB SNR are maintained across this full range. The integrated reference, robust LVDS interface, and QFN package with exposed thermal pad support reliable thermal management in high-temperature, high-vibration environments typical of engine control modules and battery management systems.
