Product details
Overview
LTC2367CMS-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit pseudo-differential unipolar successive approximation register (SAR) ADC with 500ksps throughput, 94.7dB typical SNR at 2kHz, ±0.75LSB max INL, and guaranteed no missing codes. It operates from a single 2.5V supply, supports 2.5V–5.1V external reference, and delivers high-speed precision in compact MSOP-16 packaging for space-constrained instrumentation.
For engineers reviewing the LTC2367CMS-16#PBF datasheet, LTC2367CMS-16#PBF pinout, LTC2367CMS-16#PBF application, or LTC2367CMS-16#PBF equivalent, key selection considerations include its 500ksps zero-latency conversion, 6.8mW power at full rate, SPI-compatible daisy-chain interface, and guaranteed operation from 0°C to 70°C in the MSOP package.
Technical Context
The LTC2367CMS-16#PBF implements a charge-redistribution SAR architecture with internal conversion clock, eliminating external timing dependencies. Its pseudo-differential input stage accepts 0V to VREF on IN+, with IN– referenced to GND (±100mV range), enabling common-mode noise rejection without requiring true differential signal sources.
Conversion is initiated by a rising edge on CNV; BUSY goes high during acquisition and conversion (1.5µs max), then low upon data readiness. The SPI-compatible serial interface supports 1.8V–5V OVDD logic levels, daisy-chain mode via CHAIN/RDL/SDI, and MSB-first straight-binary output - all with no pipeline delay or cycle latency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full 65,536-code dynamic range with monotonic transfer function. |
| Sampling Rate | 500ksps - enables real-time capture of signals up to 250kHz Nyquist bandwidth. |
| SNR (fIN = 2kHz) | 94.7dB typical - corresponds to ~7.5 effective bits beyond DC, critical for high-fidelity signal digitization. |
| INL (max) | ±0.75LSB - ensures linearity error remains under 0.0012% of full scale, preserving measurement integrity. |
| Power (500ksps) | 6.8mW - achieved with 2.5V VDD and 2.5V OVDD, enabling battery-operated or thermally constrained designs. |
| Reference Range | 2.5V to 5.1V - allows flexible scaling of input range (e.g., 0–5V or 0–2.5V) while maintaining LSB size proportionality. |
| Operating Temp | 0°C to 70°C - specified performance across commercial temperature range in MSOP-16 package. |
Pinout & Package
Package: 16-lead plastic MSOP (3mm × 4.9mm), exposed pad not present (DFN variant has exposed pad; MSOP does not). Pin 1 is CHAIN, pin 16 is GND; pin 17 is absent in MSOP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | Low = normal 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; requires 10µF ceramic bypass to GND. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce and improve PSRR. |
| IN+ (4) | Pseudo-differential input | 0V to VREF range; sees 45pF capacitance and 40Ω switch resistance during acquisition. |
| IN– (5) | Common-mode sense | ±100mV range w.r.t. GND; must connect to system ground or remote ground sense point. |
| REF (7,8) | Reference input | 2.5V–5.1V external reference; dual pins reduce impedance and improve decoupling (47µF X5R required). |
| CNV (9) | Convert trigger | Rising-edge initiates acquisition + conversion; minimum 20ns high time required. |
| BUSY (11) | Status indicator | Active-high open-drain output signaling conversion progress (1.5µs duration). |
| RDL/SDI (12) | Configurable I/O | Function depends on CHAIN state; in chain mode, accepts serial data from upstream ADC. |
| SCK (13) | Serial clock | Accepts 10ns min period (100MHz max), synchronous to SDO data output. |
| SDO (14) | Serial data output | MSB-first straight binary; valid 9.5ns after SCK↑ (CL = 20pF); tri-state when RDL low. |
| OVDD (15) | Digital I/O supply | 1.71V–5.25V; sets logic thresholds for all digital pins; bypass with 0.1µF ceramic. |
Key Features
| Feature | Design Value |
|---|---|
| No missing codes at 16 bits | Guaranteed monotonicity across full temperature range - eliminates code ambiguities in closed-loop control. |
| Internal conversion clock | Removes need for external timing circuitry; simplifies layout and reduces BOM count in timing-critical systems. |
| Auto power-down between conversions | Reduces idle current to 0.9µA (typ), scaling power linearly with sample rate - ideal for burst-mode sensing. |
| SPI-compatible daisy-chain mode | Enables synchronized multi-channel sampling with single host interface - cuts GPIO usage and PCB routing complexity. |
| Guaranteed operation to 70°C | Full AC/DC specs validated across commercial temperature range - suitable for industrial enclosures without active cooling. |

FAQ
What is the maximum sampling frequency of the LTC2367CMS-16#PBF?
The LTC2367CMS-16#PBF achieves a maximum sampling frequency of 500ksps with no cycle latency. This is guaranteed across the full 0°C to 70°C operating temperature range and supported by internal timing - no external clock required. At this rate, the device consumes 6.8mW and maintains 94.7dB typical SNR at 2kHz input.
Does the LTC2367CMS-16#PBF require an external reference voltage?
Yes, the LTC2367CMS-16#PBF requires an external reference voltage applied to the REF pins (7 and 8). The reference range is 2.5V to 5.1V, and performance metrics like SNR and INL are specified with VREF = 5V. A low-noise, low-drift reference such as the LTC6655-5 is recommended to achieve datasheet specifications.
How does the daisy-chain mode work on the LTC2367CMS-16#PBF?
Daisy-chain mode is enabled by driving the CHAIN pin (1) high. In this mode, RDL/SDI (12) becomes a serial data input, accepting output from the previous device in the chain, while SDO (14) drives the next device. All devices share one SCK and CNV, enabling synchronized multi-ADC sampling with minimal host interface overhead.
What is the input structure of the LTC2367CMS-16#PBF - differential or single-ended?
The LTC2367CMS-16#PBF features a pseudo-differential unipolar input structure: IN+ accepts 0V to VREF, while IN– serves as a ground-sense node with ±100mV range. This configuration rejects common-mode noise without requiring true differential signal sources, simplifying front-end design versus fully differential ADCs.
What package type and lead finish does the LTC2367CMS-16#PBF use?
The LTC2367CMS-16#PBF uses a 16-lead plastic MSOP package (3mm × 4.9mm) with lead-free (Pb-free) finish, compliant with RoHS Directive 2011/65/EU. It is rated for 0°C to 70°C operation and features four dedicated GND pins (3, 6, 10, 16) to enhance grounding integrity.
