Product details

Overview

LTC2376HMS-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit, 250ksps 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 reference). It operates from a single 2.5V analog supply and supports 1.8V–5V I/O logic, enabling high-precision data acquisition in thermally demanding industrial and medical systems.

For engineers reviewing the LTC2376HMS-16#TRPBF datasheet, LTC2376HMS-16#TRPBF pinout, LTC2376HMS-16#TRPBF application, or LTC2376HMS-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes operation across –40°C to +125°C, digital gain compression (DGC) for single-supply amplifier interfacing, and daisy-chain SPI compatibility with zero cycle latency.

Technical Context

The LTC2376HMS-16#TRPBF implements a charge redistribution capacitor DAC (CDAC) architecture with internal conversion clock, eliminating external timing dependencies. Its fully differential input stage accepts ±VREF signals while maintaining 86dB CMRR at 125kHz and supports digital gain compression to map full-scale input from 0.5V–4.5V (with 5V reference), enabling use with single-rail amplifiers.

Conversion is initiated by a rising edge on CNV; BUSY goes high during conversion and returns low upon completion. The SPI-compatible serial interface supports MSB-first 2's complement output, daisy-chain mode via CHAIN/RDL/SDI pins, and 100MHz SCK operation - all while guaranteeing no pipeline delay or cycle latency across its full temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	16-bit with guaranteed no missing codes over –40°C to +125°C
Sampling Rate	250ksps maximum throughput; 4µs conversion cycle time
SNR	97dB typical at fIN = 2kHz, VREF = 5V - enables >15.8 effective bits
INL	±0.5LSB maximum over full temperature range - ensures monotonicity and calibration stability
Power Dissipation	3.4mW at 250ksps; 315µW in power-down mode (H-grade)
Digital Gain Compression	Enabled by grounding REF/DGC pin; shifts full-scale input to 10%–90% of ±VREF - eliminates need for negative amplifier supply
Reference Range	2.5V to 5.1V external reference - supports flexible signal scaling and headroom management

Pinout & Package

Package: 16-lead plastic MSOP (H-grade, –40°C to +125°C operating range); exposed pad not present (DFN variant has exposed pad, MSOP does not).

Pin/Terminal	Circuit Role	Design Meaning
CHAIN (1)	Mode selector	Low = normal SPI mode (RDL/SDI = bus enable); high = daisy-chain mode (RDL/SDI = serial data input)
VDD (2)	Analog supply	2.375V–2.625V; powers core ADC and internal oscillator - requires 10µF ceramic bypass to GND
IN+, IN– (4,5)	Differential analog inputs	Accept ±VREF input range; 45pF sampling capacitance + 40Ω switch RON - require low-impedance drive or buffering
REF (7)	Reference voltage input	2.5V–5.1V external reference; decoupled with 47µF X5R ceramic capacitor - sets LSB size (e.g., 152µV at 5V ref)
REF/DGC (8)	Reference/DGC control	Tied to REF = standard ±VREF range; tied to GND = DGC enabled (0.1×VREF to 0.9×VREF full-scale mapping)
CNV (9)	Convert trigger	Rising-edge–initiated conversion start; powers up device and begins acquisition phase
BUSY (11)	Conversion status indicator	High during conversion; low when result ready - used for timing synchronization without polling
RDL/SDI (12)	Serial interface control/data	Bus enable (CHAIN = low) or serial data input (CHAIN = high) - compatible with 1.8V–5V logic levels
SCK (13)	Serial clock input	Up to 100MHz; controls MSB-first data shift-out on SDO - timing validated across OVDD = 1.71V–5.25V
SDO (14)	Serial data output	2's complement 16-bit result; tri-state when RDL = low - supports multi-device daisy-chain readout
OVDD (15)	I/O supply	1.71V–5.25V; sets logic thresholds for all digital pins - bypassed with 0.1µF capacitor

Key Features

Feature	Design Value
Digital Gain Compression (DGC)	Enables 0.5V–4.5V input swing with 5V reference, allowing single 5.5V supply for driving amplifiers like LT6350
No Missing Codes at 16 Bits	Guaranteed over –40°C to +125°C - eliminates code ambiguities in closed-loop control and safety-critical monitoring
Zero Cycle Latency	Immediate data availability after conversion - critical for real-time feedback loops and deterministic sampling
Internal Conversion Clock	Removes dependency on external clock source - simplifies layout and reduces jitter-sensitive timing paths
Auto Power-Down Between Conversions	Reduces average power to 315µW at low sample rates - extends battery life in portable instrumentation

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
AD7960BCPZ-RL7	18-bit, 5Msps, 2.5V supply, but requires external reference and separate VIO supply; no integrated DGC	Higher resolution/speed, but larger PCB footprint and more complex power sequencing; lacks DGC for single-supply amplifier interface	Select when >16-bit resolution and >1Msps sampling are mandatory; avoid if system-level cost, board space, or single-supply amplifier integration are constraints.
ADS8860IDRCT	16-bit, 1MSPS, 2.5–5V supply, SPI interface, but only rated to 85°C and lacks DGC or guaranteed no-missing-codes spec	Lower thermal robustness; no DGC function limits amplifier supply flexibility; missing-codes not guaranteed over temperature	Select for commercial-temperature, high-speed applications where cost is primary; avoid for industrial/medical deployments requiring guaranteed monotonicity at 125°C.

Compared with AD7960BCPZ-RL7 and ADS8860IDRCT, the LTC2376HMS-16#TRPBF uniquely balances 125°C operation, integrated DGC, and guaranteed no-missing-codes - making it optimal for thermally constrained, amplifier-integrated, and safety-aware designs where 250ksps and 16-bit fidelity are sufficient.

FAQ

What is the operating temperature range for the LTC2376HMS-16#TRPBF?

The LTC2376HMS-16#TRPBF is an H-grade part rated for continuous operation from –40°C to +125°C. This specification is guaranteed across all key parameters including INL (±0.5LSB max), SNR (97dB typ), and power consumption (3.4mW at 250ksps), making it suitable for under-hood automotive sensors, industrial motor drives, and sealed medical enclosures.

Does the LTC2376HMS-16#TRPBF support daisy-chain configuration?

Yes, the LTC2376HMS-16#TRPBF supports daisy-chain mode via the CHAIN pin (Pin 1). When CHAIN is high, the RDL/SDI pin functions as serial data input, allowing multiple LTC2376HMS-16#TRPBF devices to share a single SPI bus with synchronized CNV triggering - verified in the datasheet timing diagrams and functional block diagram.

How does Digital Gain Compression (DGC) work on the LTC2376HMS-16#TRPBF?

Digital Gain Compression on the LTC2376HMS-16#TRPBF is activated 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–4.5V with a 5V reference - enabling single-supply amplifier operation while preserving full 16-bit resolution and linearity.

What reference voltage range is supported by the LTC2376HMS-16#TRPBF?

The LTC2376HMS-16#TRPBF accepts an external reference voltage (REF pin, Pin 7) from 2.5V to 5.1V. The reference directly defines the full-scale differential input range (±VREF) and LSB size - for example, a 5V reference yields 152µV per LSB. Reference current is 0.16–0.2mA and scales linearly with sample rate.

Is the LTC2376HMS-16#TRPBF pin-compatible with other variants in the LTC2376-16 family?

Yes, the LTC2376HMS-16#TRPBF shares identical pinout and package (16-lead MSOP) with LTC2376CMS-16#TRPBF and LTC2376IMS-16#TRPBF. All variants use the same footprint, thermal pad (none for MSOP), and electrical interface - only the temperature grade (0°C–70°C, –40°C–85°C, or –40°C–125°C) differs between them.
