Product details
Overview
LTC2392ILX-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 and supports both parallel and serial interfaces, targeting high-fidelity data acquisition in industrial instrumentation and medical imaging systems.
For engineers reviewing the LTC2392ILX-16#PBF datasheet, LTC2392ILX-16#PBF pinout, LTC2392ILX-16#PBF application, or LTC2392ILX-16#PBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes operation, internal reference tempco (±20ppm/°C max), 1300ns conversion time, 110mW power dissipation at full throughput, and –40°C to +85°C extended temperature rating.
Technical Context
The LTC2392ILX-16#PBF implements a charge-redistribution SAR architecture with a precision internal 4.096V reference buffer and on-chip oscillator, eliminating external timing components. Its fully differential analog front-end accepts ±VREF inputs with 70dB common-mode rejection and 50MHz –3dB input bandwidth.
It supports dual interface modes: 16-bit parallel output (D0–D15) with BUSY/RD/CS control, and 16-bit serial output (MSB-first on SDOUT) synchronized to SCLK, selectable via SER/PAR pin. No pipeline delay or cycle latency ensures deterministic timing for real-time control loops.
Key Specifications

FAQ
What is the operating temperature range of the LTC2392ILX-16#PBF?
The LTC2392ILX-16#PBF is rated for operation from –40°C to +85°C, meeting industrial-grade environmental requirements. This is confirmed by its "I" grade designation in the part number and validated across all key specifications including INL, SNR, and reference tempco in the official datasheet.
Does the LTC2392ILX-16#PBF require an external clock source?
No, the LTC2392ILX-16#PBF includes an internal oscillator that sets the conversion timing, eliminating the need for an external clock. This simplifies system design and improves timing robustness-especially in noise-sensitive environments where external clock routing could induce jitter.
Can the LTC2392ILX-16#PBF operate with a 3.3V I/O supply?
Yes, the LTC2392ILX-16#PBF supports 1.8V to 5V I/O voltage (OVP), so it can interface directly with 3.3V logic without level shifters. The digital outputs (D0–D15, BUSY, RD, etc.) are compatible with 3.3V CMOS thresholds, and input VIH/VIL specs confirm reliable operation at 3.3V OVP.
How does the internal reference of the LTC2392ILX-16#PBF compare to external references?
The LTC2392ILX-16#PBF internal reference provides 4.096V ±0.5% initial accuracy and ±20ppm/°C max tempco-sufficient for most industrial applications. For higher precision, an external reference like the LT1790-4.096 (±0.05%, ±10ppm/°C) can be used by grounding REFOUT and connecting to REFIN, as documented in the datasheet.
What is the significance of "no missing codes" in the LTC2392ILX-16#PBF specification?
"No missing codes" guarantees that every possible 16-bit digital output code (0 to 65,535) appears at least once across the full input range. This is essential for open-loop control, histogram-based analysis, and metrology applications where code gaps would introduce nonlinearity or measurement bias-guaranteed for LTC2392ILX-16#PBF over its entire –40°C to +85°C range.
