Product details
Overview
LTC2392HLX-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter with ±4.096V fully differential input range, ±2LSB INL (max), 94dB SNR (typ), and integrated 4.096V reference. It operates from a single 5V supply with 1.8V–5V I/O compatibility and supports industrial high-temperature operation up to 125°C - ideal for precision data acquisition in harsh environments.
For engineers reviewing the LTC2392HLX-16#PBF datasheet, LTC2392HLX-16#PBF pinout, LTC2392HLX-16#PBF application, or LTC2392HLX-16#PBF equivalent, key selection criteria include guaranteed no missing codes at 16 bits, absence of pipeline delay, dual parallel/serial interface flexibility, internal conversion clock, and validated performance across –40°C to +125°C.
Technical Context
The LTC2392HLX-16#PBF implements a charge-redistribution SAR architecture with a precision internal 4.096V reference (±20ppm/°C max tempco) and differential input sampling circuitry. Its conversion timing is governed by an internal oscillator, eliminating external clock dependency and ensuring consistent 1300ns conversion time and 685ns acquisition time across temperature.
It supports both offset binary and two's complement output formats via OB/2C control, byte-swapped data ordering via BYTESWAP, and configurable serial (SDIN/SDOUT/SCLK) or parallel (D0–D15) interfaces - all with no cycle latency and zero pipeline delay, enabling deterministic real-time signal capture in closed-loop control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 discrete output levels with guaranteed no missing codes over full temperature range. |
| Sampling Rate | 500ksps - enables real-time digitization of signals up to 250kHz Nyquist bandwidth without undersampling. |
| SNR | 94dB (typ) at fIN = 20kHz - ensures >15.6 effective number of bits (ENOB) for high-fidelity signal reconstruction. |
| INL | ±2LSB (max) - limits integral nonlinearity error to ≤0.003% of full-scale, critical for calibration-sensitive instrumentation. |
| Input Range | ±4.096V differential - supports maximum dynamic range with 125µV LSB step size when using internal 4.096V reference. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, downhole oil & gas, and industrial motor drive applications. |
| Power Dissipation | 110mW at 500ksps - enables high-speed precision conversion while maintaining thermal stability in compact enclosures. |
Pinout & Package
48-lead 7mm × 7mm plastic LQFP package with exposed thermal pad (Pin 49 = GND). All GND pins (1, 5, 7, 20, 35, 41, 44, 48) and exposed pad must be soldered to a solid ground plane for optimal noise immunity and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN– (Pins 43, 42) | Differential analog inputs | Accept ±4.096V differential signal; require matched layout and low-noise driver (e.g., LT6350) for full 94dB SNR performance. |
| CNVST (Pin 34) | Conversion start trigger | Falling-edge initiated; independent of CS/RD, enabling precise timing control in synchronous sampling systems. |
| BUSY (Pin 29) | Conversion status indicator | High during conversion; falling edge signals data-ready - usable as hardware interrupt or clock for downstream logic. |
| SER/PAR (Pin 4) | Interface mode select | Logic low = 16-bit parallel output (D0–D15); logic high = serial interface (SDIN/SDOUT/SCLK) for reduced pin count. |
| REFOUT / REFIN (Pins 37, 38) | Reference I/O pair | Shorted for internal 4.096V reference use; REFIN accepts external reference (2.5V–4.096V) when REFOUT grounded. |
| OVP (Pin 18) | Digital I/O supply | 1.8V–5V programmable voltage - allows direct interfacing with FPGA/ASIC I/O banks without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay, zero cycle latency | Enables immediate readout after BUSY↓ - essential for real-time feedback loops and event-triggered acquisition. |
| Internal 4.096V reference (±20ppm/°C max) | Eliminates external reference component cost and board space; maintains <0.1% full-scale drift over –40°C to +125°C. |
| Parallel + serial interface modes | Hardware-selectable via SER/PAR pin - supports high-throughput FPGA interfacing (parallel) or microcontroller-constrained designs (serial). |
| 1.8V–5V I/O voltage (OVP) | Direct compatibility with modern low-voltage logic families (1.8V, 2.5V, 3.3V, 5V) without translation circuitry. |
| Guaranteed operation to +125°C | Qualified per H-grade spec - enables deployment in engine control units, power inverters, and aerospace avionics without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1MSPS, single-ended input only; external reference required; 1.8V supply only; no internal oscillator. | Lacks differential input and integrated reference - requires external driver and reference circuitry, increasing BOM and layout complexity. | Choose when higher speed (1MSPS) is mandatory and system already provides precision external reference and differential-to-single-ended conversion. |
| AD7606BSTZ | 16-bit, 200ksps, simultaneous sampling octal ADC; ±10V input range; internal reference (±10ppm/°C); SPI-only interface. | Slower throughput, fixed SPI interface, and larger 64-lead LQFP - unsuitable for single-channel 500ksps deterministic timing-critical use cases. | Choose for multi-channel synchronized acquisition where channel count outweighs speed requirement and SPI interface suffices. |
Compared with ADS8860IDRCT and AD7606BSTZ, the LTC2392HLX-16#PBF uniquely combines 500ksps speed, true differential input, integrated low-drift reference, and dual interface flexibility in a thermally robust H-grade package - making it optimal for single-channel, latency-sensitive, high-accuracy embedded systems.

FAQ
What is the maximum operating temperature for the LTC2392HLX-16#PBF?
The LTC2392HLX-16#PBF is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature limited to 150°C. This H-grade qualification makes it suitable for under-hood automotive, industrial motor control, and downhole instrumentation applications where thermal resilience is critical. The LTC2392HLX-16#PBF maintains full electrical specifications across this range.
Does the LTC2392HLX-16#PBF require an external clock source?
No, the LTC2392HLX-16#PBF includes an internal oscillator that sets the conversion timing - eliminating the need for an external clock and simplifying system design. Conversion time is fixed at 1300ns with 685ns acquisition time, both guaranteed over temperature. External clocks are not supported; timing is fully self-contained within the LTC2392HLX-16#PBF.
Can the LTC2392HLX-16#PBF operate with a 3.3V I/O supply?
Yes, the LTC2392HLX-16#PBF supports 1.8V to 5V digital I/O voltage via the OVP pin (Pin 18). When powered with 3.3V on OVP, all digital outputs (D0–D15, SDOUT, BUSY, etc.) swing rail-to-rail between 0V and 3.3V, and inputs (CS, RD, CNVST, etc.) recognize logic thresholds compatible with 3.3V CMOS levels - enabling direct interfacing with 3.3V FPGAs and microcontrollers without level shifters.
How does the internal reference of the LTC2392HLX-16#PBF compare to external references in accuracy?
The LTC2392HLX-16#PBF internal reference provides 4.096V ±0.5% initial accuracy and ±20ppm/°C max temperature coefficient - sufficient for most high-precision applications. For tighter requirements, an external reference like the LT1790-4.096 (0.05% initial accuracy, ±10ppm/°C) can be used by connecting it to REFIN and grounding REFOUT. The LTC2392HLX-16#PBF reference buffer remains active in both configurations.
Is the LTC2392HLX-16#PBF pin-compatible with other variants in the LTC2392 family?
Yes, all LTC2392-16 variants - including LTC2392CLX-16#PBF, LTC2392ILX-16#PBF, and LTC2392HLX-16#PBF - share identical 48-lead LQFP pinout and footprint. Only the temperature grade and part marking differ; electrical functionality, timing, and interface behavior are fully consistent. This allows drop-in replacement across C/I/H grades when thermal requirements change.
