Product details

Overview

LTC2367CMS-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit pseudo-differential unipolar successive approximation register (SAR) ADC optimized for high-speed, low-noise data acquisition. It operates from a single 2.5V supply, supports 0V to VREF input range (VREF = 2.5V–5.1V), delivers 500ksps throughput with no pipeline delay, achieves ±0.75LSB INL max and 94.7dB SNR (typ), and is housed in a 16-lead MSOP package rated for 0°C to 70°C operation.

For engineers reviewing the LTC2367CMS-16#TRPBF datasheet, LTC2367CMS-16#TRPBF pinout, LTC2367CMS-16#TRPBF application, or LTC2367CMS-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, daisy-chain SPI interface compatibility across 1.8V–5V logic, internal conversion clock, auto power-down at 6.8µW idle, and validated operation up to 125°C in H-grade variants.

Technical Context

The LTC2367CMS-16#TRPBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, sampling pseudo-differential inputs (IN+, IN–) using an internal oscillator-controlled conversion cycle. Its acquisition phase draws transient current into 45pF input capacitance, while hold-mode leakage remains below ±1µA.

It features dual-supply operation: 2.375V–2.625V on VDD for analog core and 1.71V–5.25V on OVDD for flexible I/O interfacing. The RDL/SDI pin serves dual roles-bus enable in normal mode or serial data input in daisy-chain mode-controlled by the CHAIN pin, enabling scalable multi-ADC systems without external logic.

Key Specifications

REF (7,8)	Reference voltage input	Dual-pin connection for low-impedance decoupling; requires 47µF X5R ceramic capacitor
CNV (9)	Convert trigger	Rising-edge initiates acquisition and conversion; no minimum pulse width required
BUSY (11)	Conversion status indicator	Active-high signal indicates ongoing conversion; t_BUSYLH = 13ns max delay from CNV↑
RDL/SDI (12)	Serial interface control/data	Bus enable (normal mode) or serial data input (chain mode); OVDD-referenced logic
SCK (13)	Serial clock input	Supports up to 100MHz SCK (10ns period); timing-critical for data capture alignment
SDO (14)	Serial data output	MSB-first straight-binary output; valid 9.5ns after SCK↑ (CL = 20pF)
OVDD (15)	I/O supply	1.71V–5.25V logic supply; enables direct interfacing with 1.8V/2.5V/3.3V/5V microcontrollers

Key Features

Feature	Design Value
No pipeline latency	Zero-cycle delay between CNV edge and BUSY assertion enables deterministic timing in real-time control loops

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit SAR ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD7960BCPZ	18-bit resolution, 5Msps, requires external reference and separate V_DRIVE supply; consumes 34mW at full speed	Higher resolution and speed suit metrology-grade bench instruments, not portable or low-power systems	Select AD7960BCPZ only when >16-bit ENOB and >1Msps are mandatory; verify layout support for 5Msps timing closure
ADS8860IDRCT	16-bit, 1MSPS, SPI interface, but only 89dB SNR (typ) and ±1.5LSB INL; single-supply 2.5V–3.6V operation	Lower noise/linearity limits use in precision medical or process control; better suited for cost-sensitive industrial logging	Choose ADS8860IDRCT for lower-cost, lower-performance applications where 94dB SNR is not required

Compared with AD7960BCPZ and ADS8860IDRCT, the LTC2367CMS-16#TRPBF uniquely balances 94.7dB SNR, ±0.75LSB INL, 500ksps throughput, and 6.8mW power in a compact MSOP - making it optimal for portable, battery-aware, high-fidelity data acquisition where neither ultra-high speed nor ultra-low cost dominates the design trade-off.

FAQ

What is the operating temperature range for the LTC2367CMS-16#TRPBF?

The LTC2367CMS-16#TRPBF is specified for 0°C to 70°C operation. This commercial-grade temperature range aligns with standard industrial and portable equipment ambient conditions. For extended-range applications, the LTC2367HMS-16#TRPBF variant supports –40°C to 125°C and shares identical pinout and functionality.

Does the LTC2367CMS-16#TRPBF require an external clock source?

No, the LTC2367CMS-16#TRPBF integrates an internal oscillator that sets conversion timing, eliminating the need for an external clock. This simplifies system design and improves jitter immunity. External clocking is not supported - all timing derives from the internal oscillator synchronized to the CNV input edge.

Can the LTC2367CMS-16#TRPBF interface directly with a 1.8V microcontroller?

Yes, the LTC2367CMS-16#TRPBF supports 1.8V logic levels via its OVDD pin. When OVDD = 1.8V, VIH = 1.44V (min) and VIL = 0.36V (max), ensuring reliable communication with 1.8V I/O domains without level shifters. VDD remains fixed at 2.5V for analog operation.

What is the purpose of the CHAIN pin on the LTC2367CMS-16#TRPBF?

The CHAIN pin (Pin 1) configures the serial interface mode: when low, RDL/SDI acts as a bus-enable input; when high, RDL/SDI becomes a serial data input for daisy-chain operation. This allows multiple LTC2367CMS-16#TRPBF devices to share one SCK/SDO pair, reducing host interface complexity in multi-channel systems.

How does the LTC2367CMS-16#TRPBF achieve low power consumption at partial throughput rates?

The LTC2367CMS-16#TRPBF automatically powers down its analog core between conversions. At 500sps, total supply current drops to 0.9µA (typ), reducing power dissipation to 6.8µW - a 1000× reduction versus full-rate operation. This feature is fully automatic and requires no software control or mode register writes.
