Product details
Overview
LTC2364CMS-18#TRPBF from Analog Devices (formerly Linear Technology) is an 18-bit, 250ksps pseudo-differential unipolar successive approximation register (SAR) ADC operating from a single 2.5V supply. It delivers 97dB typical SNR, ±2.5LSB max INL, and guaranteed no missing codes at full 18-bit resolution, with VREF support from 2.5V to 5.1V. It is deployed in high-speed data acquisition systems requiring low power (3.4mW at full rate) and high DC/AC accuracy across industrial temperature ranges.
For engineers reviewing the LTC2364CMS-18#TRPBF datasheet, LTC2364CMS-18#TRPBF pinout, LTC2364CMS-18#TRPBF application, or LTC2364CMS-18#TRPBF equivalent, key selection criteria include its 250ksps throughput with zero cycle latency, SPI-compatible serial interface supporting 1.8V–5V I/O, internal conversion clock, and MSOP-16 package with guaranteed operation to +70°C.
Technical Context
The LTC2364CMS-18#TRPBF implements a charge-redistribution SAR architecture with a pseudo-differential input stage where IN+ accepts 0V to VREF and IN– operates as a ground-sense node (±100mV range). Conversion is initiated by a rising edge on CNV, with BUSY indicating active conversion and SDO outputting straight-binary 18-bit data MSB-first on SCK rising edges.
It features daisy-chain mode via CHAIN pin control and RDL/SDI reconfiguration, internal oscillator-based timing eliminating external clock dependencies, and automatic power-down between conversions-reducing current to 0.9µA in idle state. The device supports simultaneous 2.5V analog core (VDD) and flexible 1.71V–5.25V digital I/O (OVDD) supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 18-bit - guarantees monotonic transfer function and no missing codes across full temperature range. |
| Sampling Rate | 250ksps - enables real-time capture of signals up to 125kHz Nyquist bandwidth without pipeline delay. |
| SNR | 97dB typ @ fIN = 2kHz, VREF = 5V - defines usable dynamic range of ~116dBFS for precision measurement applications. |
| INL | ±2.5LSB max - limits end-point linearity error to ±48µV at 5V reference, critical for calibration-sensitive systems. |
| Power Dissipation | 3.4mW @ 250ksps - enables battery-powered instrumentation with thermal budget under 5mW. |
| Reference Range | 2.5V to 5.1V - allows system-level trade-off between input range and LSB size (19µV at 5V, 9.5µV at 2.5V). |

Pinout & Package
Package: 16-lead plastic MSOP (MS package), 3mm × 4.9mm body, exposed pad not present (DFN variant has exposed GND pad; MSOP does not).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode control input | Selects normal mode (RDL/SDI = bus enable) or daisy-chain mode (RDL/SDI = SDI); logic referenced to OVDD. |
| VDD (2) | Analog core supply | 2.5V ±62.5mV supply; bypassed with 10µF ceramic capacitor; powers internal SAR and reference buffer. |
| GND (3,6,10,16) | Analog/digital ground | Four dedicated ground pins minimize ground bounce and improve PSRR; must be connected to common low-impedance plane. |
| IN+ (4) | Pseudo-differential analog input | Accepts 0V to VREF input voltage; sampled via 45pF capacitor and 40Ω switch; requires low-impedance drive or buffering. |
| IN– (5) | Ground sense reference | ±100mV range relative to GND; used to reject common-mode noise; tied directly to local ground or remote sense point. |
| REF (7,8) | Reference voltage inputs | Dual-pin connection for 2.5V–5.1V external reference; decoupled with 47µF X5R ceramic capacitor near pin. |
| CNV (9) | Convert trigger input | Rising-edge–initiated conversion start; minimum pulse width 20ns; powers up ADC and begins acquisition phase. |
| BUSY (11) | Conversion status indicator | Active-high open-drain output; asserts high at CNV↑ and deasserts within 3µs of conversion completion. |
| RDL/SDI (12) | Configurable serial I/O | In normal mode: bus enable for SDO tri-state; in chain mode: serial data input for daisy-chained configuration. |
| SCK (13) | Serial clock input | Accepts 10ns min period (100MHz max); controls data shift-out timing on SDO; logic level referenced to OVDD. |
| SDO (14) | Serial data output | 18-bit straight-binary output MSB-first; valid 9.5ns after SCK↑; driven to OVDD/GND levels per VIH/VIL thresholds. |
| OVDD (15) | Digital I/O supply | 1.71V–5.25V supply setting logic thresholds; enables interoperability with 1.8V, 2.5V, 3.3V, or 5V host controllers. |
Key Features
| Feature | Design Value |
|---|---|
| No cycle latency | Enables deterministic real-time sampling - first conversion completes within 4µs of CNV↑, with no pipeline delay or dead time. |
| Auto power-down | Reduces quiescent current to 0.9µA between conversions, scaling power linearly with sample rate for burst-mode operation. |
| SPI-compatible interface | Supports standard 4-wire SPI protocol plus daisy-chain mode - simplifies multi-channel designs without additional GPIO or FPGA logic. |
| Internal conversion clock | Eliminates need for external timing components or clock distribution networks - reduces BOM count and layout complexity. |
| Pseudo-differential input | Rejects common-mode noise on IN+/IN– pair while maintaining unipolar 0V–VREF range - improves EMI immunity without differential driver overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8864IDRCT | 18-bit, 250ksps, SPI interface, but requires external reference and separate VIO supply; ±1.5LSB INL max; no daisy-chain mode. | Designed for lower-cost test equipment where reference flexibility outweighs integrated features. | Choose when external reference control is required and daisy-chain is unnecessary; verify REF drive capability matches ADS8864's 1.5mA IREF spec. |
| AD7960BCPZ-RL7 | 18-bit, 5Msps, pseudo-differential, but consumes 33mW at full speed; requires LVDS or parallel interface; no internal oscillator. | Targeted at ultra-high-speed imaging or radar digitizers where throughput >1Msps is mandatory. | Choose only if sampling rate >1Msps is needed; avoid for battery-powered or thermally constrained designs due to 10× higher power. |
Compared with ADS8864IDRCT and AD7960BCPZ-RL7, the LTC2364CMS-18#TRPBF uniquely combines internal clocking, daisy-chain support, and 3.4mW power at 250ksps - making it optimal for space-constrained, multi-channel, low-power precision acquisition where timing simplicity and thermal management are critical.

FAQ
What is the maximum recommended reference voltage for LTC2364CMS-18#TRPBF?
The LTC2364CMS-18#TRPBF supports VREF from 2.5V to 5.1V per Absolute Maximum Ratings and Electrical Characteristics tables. Operation at 5.1V maximizes input range and minimizes LSB size impact on noise floor, but requires a reference capable of sourcing up to 0.2mA at 250ksps. The LTC6655-5 is validated for this use case.
Does LTC2364CMS-18#TRPBF require external clocking for conversion timing?
No. The LTC2364CMS-18#TRPBF integrates an internal oscillator that sets conversion time (tCONV = 1.9–3µs), eliminating dependency on external clocks. Only the SCK signal is needed for serial data readout - simplifying timing design and reducing jitter-sensitive components.
Can LTC2364CMS-18#TRPBF operate with a 1.8V digital interface supply?
Yes. The OVDD pin accepts 1.71V to 5.25V, enabling direct interfacing with 1.8V logic families. VIH and VIL thresholds scale with OVDD (0.8•OVDD and 0.2•OVDD), and SDO output swing complies with 1.8V CMOS levels - confirmed in Digital Inputs and Outputs specifications.
What is the purpose of the IN– pin on LTC2364CMS-18#TRPBF?
The IN– pin on LTC2364CMS-18#TRPBF serves as a ground-sense node with ±100mV input range, enabling pseudo-differential operation. It rejects common-mode noise while allowing unipolar 0V–VREF input on IN+, without requiring true differential signal sources or drivers - reducing system cost and complexity.
Is LTC2364CMS-18#TRPBF pin-compatible with other variants in the LTC2364-18 family?
Yes. All LTC2364-18 variants - including LTC2364IMS-18#TRPBF (–40°C to +85°C) and LTC2364HMS-18#TRPBF (–40°C to +125°C) - share identical MSOP-16 pinout and footprint. Only temperature grade and tape-and-reel packaging differ; no PCB redesign is needed when upgrading grades.
