Product details

Overview

LTC2377IMS-16#TRPBF 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, low power, and thermal robustness.

For engineers reviewing the LTC2377IMS-16#TRPBF datasheet, LTC2377IMS-16#TRPBF pinout, LTC2377IMS-16#TRPBF application, or LTC2377IMS-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes operation, daisy-chain SPI interface compatibility (1.8V–5V I/O), internal conversion clock, −40°C to +85°C industrial temperature rating, and MSOP-16 package with exposed pad grounding.

Technical Context

The LTC2377IMS-16#TRPBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, enabling zero-cycle-latency conversions and no pipeline delay. Its internal oscillator eliminates external clock dependency, while auto power-down between conversions scales quiescent current from 2.7mA (500ksps) to 0.9µA (power-down mode).

Digital gain compression (DGC) redefines full-scale input range from ±VREF to 0.1×VREF to 0.9×VREF when REF/DGC is grounded - preserving 16-bit resolution while allowing single-supply (e.g., +5.5V) driver amplifiers. The ADC supports both normal and daisy-chain SPI modes via the CHAIN pin, with SDO output in 2's complement format and BUSY-driven timing control.

Pin/Terminal	Circuit Role	Design Meaning
CHAIN (1)	Mode selector	High enables daisy-chain SPI; low configures RDL/SDI as bus enable - determines serial topology without external logic.
VDD (2)	Analog supply	2.5V ±62.5mV supply; bypassed with 10µF ceramic capacitor - powers core ADC and sets reference scaling accuracy.
GND (3,6,10,16)	Ground reference	Four dedicated GND pins minimize ground bounce and ensure stable common-mode rejection during sampling.
IN+, IN− (4,5)	Differential analog inputs	Accept ±V_REF swing; 45pF input capacitance and 40Ω switch R_ON define acquisition settling requirements.
REF (7)	Reference voltage input	2.5V–5.1V external reference; decoupled with 47µF X5R capacitor - directly sets LSB size (e.g., 152µV at 5V).
REF/DGC (8)	Reference mode control	GND enables DGC (0.1–0.9×V_REF range); tied to REF disables DGC - selects between bipolar full-scale or compressed input headroom.
CNV (9)	Convert trigger	Rising edge initiates acquisition and conversion; no minimum pulse width required - simplifies timing-critical microcontroller interfaces.
BUSY (11)	Conversion status	Active-high open-drain output; indicates conversion progress - enables polling or interrupt-driven data readout.
RDL/SDI (12)	Serial data control/input	In normal mode: bus enable; in chain mode: serial data input - supports cascaded ADC configurations with shared SCK/SDO.
SCK (13)	Serial clock input	Up to 100MHz clock (10ns period); rising-edge sampled - defines data transfer rate and synchronizes multi-device reads.
SDO (14)	Serial data output	2's complement 16-bit output, MSB-first; valid within 9.5ns of SCK↑ - enables deterministic timing for FPGA or DSP capture.
OVDD (15)	I/O supply	1.71V–5.25V logic supply; sets VIH/VIL thresholds - allows direct interfacing with 1.8V, 2.5V, 3.3V, or 5V host processors.

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 (43mW).	Targets ultra-high-resolution applications (e.g., spectral analysis) where speed outweighs power constraints.	Select AD7960BCPZ-RL7 only if >16-bit ENOB and >1Msps throughput are mandatory; not drop-in due to different pinout and interface timing.
ADS8860IDRCT	16-bit, 1MSPS, 2.5–5V supply, SPI-only (no daisy-chain), lower SNR (92.5dB), no DGC.	Suitable for cost-sensitive, single-channel data loggers where thermal robustness and DGC are noncritical.	Choose ADS8860IDRCT for simpler designs without multi-ADC synchronization needs; verify layout compatibility - different MSOP-10 footprint.

Compared with AD7960BCPZ-RL7 and ADS8860IDRCT, the LTC2377IMS-16#TRPBF uniquely balances 500ksps speed, 97dB SNR, DGC-enabled single-supply drive, and industrial temperature support in a standard MSOP-16 - making it optimal for thermally constrained, multi-channel, battery-aware systems requiring verified 16-bit integrity.

FAQ

What is the maximum sampling rate of the LTC2377IMS-16#TRPBF?

The LTC2377IMS-16#TRPBF achieves a maximum sampling rate of 500ksps with no pipeline delay or cycle latency. This is guaranteed across its full operating temperature range (−40°C to +85°C) and supported by internal timing circuitry that eliminates external clock dependencies. At this rate, the device consumes 6.8mW and maintains 97dB SNR performance.

Does the LTC2377IMS-16#TRPBF support daisy-chain configuration?

Yes, the LTC2377IMS-16#TRPBF supports daisy-chain SPI operation when the CHAIN pin (Pin 1) is driven high. In this mode, the RDL/SDI pin functions as serial data input, allowing multiple LTC2377IMS-16#TRPBF devices to share a single SCK and SDO line. The SDO output remains active during chain reads, enabling synchronized multi-channel acquisition without additional control logic.

How does Digital Gain Compression (DGC) work in the LTC2377IMS-16#TRPBF?

Digital Gain Compression (DGC) in the LTC2377IMS-16#TRPBF is enabled by grounding the REF/DGC pin (Pin 8). This remaps the full-scale input range from ±VREF to 0.1×VREF to 0.9×VREF - e.g., 0.5V to 4.5V with a 5V reference. The function preserves all 16 bits of resolution while eliminating the need for a negative supply on the driving amplifier, simplifying front-end design and reducing system power.

What package type and thermal characteristics does the LTC2377IMS-16#TRPBF use?

The LTC2377IMS-16#TRPBF uses a 16-lead plastic MSOP package (4.0mm × 3.0mm) with an exposed pad connected to GND. Its thermal resistance is θ_JA = 110°C/W, and it is rated for operation from −40°C to +85°C. The exposed pad must be soldered to the PCB ground plane to ensure proper thermal performance and noise immunity in high-precision applications.

Is the LTC2377IMS-16#TRPBF pin-compatible with other members of the LTC2377 family?

Yes, the LTC2377IMS-16#TRPBF shares identical pinout and functionality with other MSOP-packaged variants (e.g., LTC2377CMS-16#TRPBF, LTC2377HMS-16#TRPBF), differing only in temperature grade and ordering suffix. All MSOP versions use the same 16-pin layout, electrical interface, and timing specifications - enabling drop-in replacement across commercial, industrial, and high-temp grades without PCB redesign.
