Product details
Overview
LTC2382IMS-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter with fully differential ±2.5V input range, 92dB SNR at 20kHz, ±2LSB INL max, and 6.5mW power consumption at full speed. It operates from a single 2.5V VDD supply and supports 1.8V–5V I/O logic via separate OVDD, enabling direct interfacing with diverse host processors in high-speed data acquisition systems.
For engineers reviewing the LTC2382IMS-16#TRPBF datasheet, LTC2382IMS-16#TRPBF pinout, LTC2382IMS-16#TRPBF application, or LTC2382IMS-16#TRPBF equivalent, key selection considerations include guaranteed 16-bit no-missing-codes operation over –40°C to +85°C, extended 1.25µs acquisition time for low-power driver compatibility, SPI-compatible serial interface with daisy-chain mode, and internal conversion clock eliminating external timing constraints.
Technical Context
The LTC2382IMS-16#TRPBF implements a proprietary sampling architecture that allows acquisition of the next sample during the current conversion cycle, enabling a 1.25µs acquisition window while maintaining 500ksps throughput and zero cycle latency. Its fully differential SAR core uses a 16-bit CDAC and precision comparator referenced to an external 2.5V source, delivering bipolar 2's complement output codes with ±2LSB integral linearity across temperature.
Timing is internally generated via an on-chip oscillator, decoupling conversion control from external clock jitter. The device features automatic power-down between conversions, reducing idle current to 0.5µA, and supports flexible digital interface voltages (OVDD = 1.71V–5.25V) independent of the 2.375V–2.625V VDD analog supply - critical for mixed-voltage system integration.

FAQ
What is the operating temperature range for the LTC2382IMS-16#TRPBF?
The LTC2382IMS-16#TRPBF is specified for operation from –40°C to +85°C, validated across this full industrial temperature range for parameters including INL (±2LSB max), SNR (92dB typ), and power consumption (6.5mW at 500ksps). This makes it suitable for deployment in uncontrolled ambient environments such as factory floors and outdoor instrumentation enclosures.
Does the LTC2382IMS-16#TRPBF require an external clock source?
No, the LTC2382IMS-16#TRPBF integrates an internal oscillator that sets conversion timing, eliminating the need for an external clock source. This simplifies system design by removing clock distribution challenges, jitter sensitivity, and associated layout constraints - a key advantage over competing SAR ADCs requiring precise external timing.
How does the daisy-chain mode work on the LTC2382IMS-16#TRPBF?
Daisy-chain mode on the LTC2382IMS-16#TRPBF is enabled by driving the CHAIN pin high, which reconfigures RDL/SDI as a serial data input. Multiple devices can be cascaded with a single SCK line, where each LTC2382IMS-16#TRPBF shifts its 16-bit result into the next device's SDO, enabling synchronized multi-channel sampling without additional control lines or FPGA resources.
What reference voltage is recommended for the LTC2382IMS-16#TRPBF?
The LTC2382IMS-16#TRPBF requires a stable 2.5V external reference. The LTC6652-2.5 is explicitly recommended in the datasheet: it provides 0.05% initial accuracy, 5ppm/°C tempco, and is specified over the same –40°C to +125°C range as the H-grade variant. Its 47µF ceramic bypass requirement matches the REF pin's charge replenishment profile at 500ksps.
Can the LTC2382IMS-16#TRPBF interface directly with a 1.8V microcontroller?
Yes, the LTC2382IMS-16#TRPBF supports 1.8V logic levels via its OVDD pin, which accepts 1.71V–5.25V. When OVDD = 1.8V, VIH = 1.44V min and VIL = 0.36V max - fully compatible with standard 1.8V CMOS I/O. The SDO, BUSY, and RDL/SDI pins operate at OVDD-referenced levels, enabling seamless connection to low-voltage hosts without level-shifting circuitry.
