Product details

Overview

LTC2377HMS-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter with ±0.5LSB INL max, 97dB SNR at 2kHz, and fully differential ±VREF input range (2.5V–5.1V). It operates from a single 2.5V supply, consumes 6.8mW at full speed, and features digital gain compression (DGC) for single-supply amplifier interfacing - used in high-speed data acquisition systems requiring precision and low power.

For engineers reviewing the LTC2377HMS-16#PBF datasheet, LTC2377HMS-16#PBF pinout, LTC2377HMS-16#PBF application, or LTC2377HMS-16#PBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes operation over –40°C to +125°C, SPI-compatible serial interface with daisy-chain mode, internal conversion clock, and DGC-enabled 0.5V–4.5V input range with 5V reference.

Technical Context

The LTC2377HMS-16#PBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, achieving no pipeline delay and zero cycle latency. Its conversion timing is governed by an internal oscillator, eliminating external clock dependency while supporting precise timing control via CNV-triggered acquisition.

Digital gain compression (DGC) is implemented via REF/DGC pin logic: when grounded, it remaps zero-scale from 0V to 0.1·VREF and full-scale from VREF to 0.9·VREF, preserving 16-bit resolution while enabling rail-to-rail input swing compatibility with single-supply op-amps like LT6350-H. Input common-mode range is fixed at VREF/2 ± 0.1V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed SAR ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD7960BCPZ-RL7	18-bit, 5Msps, 2.5V supply, no DGC, requires external reference buffer; higher power (34mW @ 5Msps).	Targeted at ultra-high-resolution applications (>16-bit) where speed justifies increased power and complexity.	Select when resolution >16-bit and sampling rate >500ksps is mandatory; avoid if DGC or 125°C operation required.
ADS8860IDRCT	16-bit, 1MSPS, 2.5–5V supply, no DGC, SPI-only (no daisy-chain), lower SNR (92.5dB), rated to 85°C only.	Suitable for cost-sensitive industrial DAQ where extended temperature range is not needed.	Choose for lower-cost designs with ambient temperature <85°C and no requirement for DGC or daisy-chain capability.

Compared with AD7960BCPZ-RL7 and ADS8860IDRCT, the LTC2377HMS-16#PBF uniquely balances 500ksps throughput, 125°C operation, DGC-enabled single-supply interfacing, and 6.8mW power - making it optimal for thermally demanding, space-constrained, and power-sensitive high-speed measurement systems.

FAQ

What is the maximum operating temperature for the LTC2377HMS-16#PBF?

The LTC2377HMS-16#PBF is specified for continuous operation from –40°C to +125°C. All key specifications-including INL (±0.5LSB), SNR (97dB), and THD (–123dB)-are guaranteed across this full H-grade temperature range, making it suitable for under-hood automotive and industrial control applications.

Does the LTC2377HMS-16#PBF require an external clock source?

No, the LTC2377HMS-16#PBF uses an internal oscillator to set conversion time, eliminating the need for an external clock. The CNV input triggers acquisition asynchronously, and timing parameters such as t_CONV (1–1.5µs) and t_CYC (2µs) are internally controlled - simplifying system design and reducing jitter sensitivity.

How does Digital Gain Compression (DGC) work on the LTC2377HMS-16#PBF?

When the REF/DGC pin is tied to GND, the LTC2377HMS-16#PBF enables DGC, mapping zero-scale code from 0V to 0.1·V_REF and full-scale code from V_REF to 0.9·V_REF. With a 5V reference, this yields a usable input range of 0.5V–4.5V, allowing single-supply amplifiers (e.g., LT6350) to drive the ADC without negative rails.

What package type is used for the LTC2377HMS-16#PBF?

The LTC2377HMS-16#PBF uses a 16-lead plastic MSOP package (5mm × 4.4mm body, 0.65mm pitch). It does not include an exposed thermal pad - unlike the DFN variant (e.g., LTC2377CDE-16#PBF) - and is compatible with standard reflow profiles for lead-free assembly.

Is the LTC2377HMS-16#PBF pin-compatible with other variants in the LTC2377-16 family?

Yes, all LTC2377-16 variants - including LTC2377CMS-16#PBF (commercial), LTC2377IMS-16#PBF (industrial), and LTC2377HMS-16#PBF (high-temp) - share identical 16-pin MSOP pinouts and electrical interfaces. Only temperature grade and screening differ; no PCB layout changes are needed when upgrading from I-grade to H-grade.
