Product details
Overview
LTC2364CMS-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit pseudo-differential unipolar successive approximation register (SAR) ADC with 250ksps throughput, ±0.75LSB INL max, 94.7dB SNR (typ), and operation from a single 2.5V supply. It supports VREF from 2.5V to 5.1V and delivers no missing codes at 16 bits - ideal for high-speed data acquisition in portable instrumentation and industrial process control.
For engineers reviewing the LTC2364CMS-16#TRPBF datasheet, LTC2364CMS-16#TRPBF pinout, LTC2364CMS-16#TRPBF application, or LTC2364CMS-16#TRPBF equivalent, key selection criteria include guaranteed 125°C operation (H-grade variant), daisy-chain SPI interface compatibility, low 3.4mW power at full rate, and pseudo-differential input architecture enabling common-mode noise rejection in noisy environments.
Technical Context
The LTC2364CMS-16#TRPBF implements a charge-redistribution SAR architecture with internal conversion clock, eliminating external timing dependencies. Its pseudo-differential input stage uses IN+ and IN– pins with ±100mV common-mode range on IN–, supporting unipolar 0V to VREF sampling while rejecting shared noise.
It features dual supply domains: 2.5V analog core (VDD) and flexible 1.8V–5.25V digital I/O (OVDD), enabling direct interfacing with mixed-voltage host systems. Conversion is initiated by CNV rising edge, with BUSY signal indicating completion and zero-cycle latency - critical for deterministic real-time sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full-scale quantization into 65,536 discrete levels with no missing codes. |
| Sampling Rate | 250ksps - enables real-time capture of signals up to 125kHz Nyquist bandwidth. |
| SNR | 94.7dB (typ, fIN = 2kHz, VREF = 5V) - corresponds to ~15.8 effective bits (ENOB) under specified conditions. |
| INL | ±0.75LSB (max) - ensures monotonicity and linearity error within ±47µV (at 5V ref). |
| Power Consumption | 3.4mW at 250ksps - enables battery-operated designs with thermal headroom in compact enclosures. |
| Reference Range | 2.5V to 5.1V - allows system-level scaling of input dynamic range without changing hardware. |
| Operating Temp | 0°C to 70°C (C-grade) - validated for commercial temperature stability per MSOP package specification. |
Pinout & Package
Package: 16-lead plastic MSOP (small-outline package), 3mm × 4.9mm footprint, exposed pad not present (unlike DFN variant). Compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | High = daisy-chain mode (RDL/SDI becomes serial input); low = normal mode (RDL/SDI enables SDO bus). |
| VDD (2) | Analog supply | 2.5V ±62.5mV core supply; bypass required with 10µF ceramic capacitor to GND. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce and improve PSRR in high-speed operation. |
| IN+ (4) | Positive analog input | Pseudo-differential input with 0V to VREF range; sees 45pF capacitance during acquisition phase. |
| IN– (5) | Common-mode sense | Accepts ±100mV relative to GND; must be tied to ground plane or remote sense point for CMRR optimization. |
| REF (7,8) | Reference voltage input | Dual-pin connection for low-impedance decoupling; requires 47µF X5R ceramic capacitor close to pins. |
| CNV (9) | Convert trigger | Rising-edge–initiated conversion; powers up ADC and starts acquisition cycle with no setup delay. |
| BUSY (11) | Status indicator | Active-high open-drain output signaling conversion in progress; synchronized to internal clock. |
| RDL/SDI (12) | Serial control/data input | Function depends on CHAIN state: bus enable (low) or serial data input (high) - supports multi-device chains. |
| SCK (13) | Serial clock | Accepts 10ns min period (100MHz max); controls MSB-first data shift timing for SDO output. |
| SDO (14) | Serial data output | 3-state output driven by OVDD; outputs straight-binary 16-bit code aligned to SCK rising edges. |
| OVDD (15) | I/O supply | 1.71V–5.25V logic interface supply; sets VIH/VIL thresholds and drives SDO/SCK/RDL/SDI/BUSY levels. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay / zero cycle latency | Enables immediate post-conversion processing without FIFO buffering or timing uncertainty. |
| Internal conversion oscillator | Removes need for external clock source or precise timing circuitry - simplifies PCB layout and BOM. |
| Auto power-down between conversions | Reduces average power proportionally to sampling rate; drops to 3.4µW at 250sps for ultra-low-power wake-on-event use. |
| SPI-compatible daisy-chain mode | Allows synchronous readout of multiple LTC2364-16 devices using single SCK/SCKCH line - cuts GPIO count in multi-channel systems. |
| Guaranteed operation to 125°C (H-grade variants) | Validated thermal performance enables deployment in engine control units, downhole tools, and industrial motor drives. |

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 | 2.5MSPS, 18-bit, differential input only; requires external reference and driver; consumes 39mW at full rate. | Targeted at higher-resolution, lower-throughput metrology; lacks pseudo-differential flexibility and integrated reference buffer. | Select when ENOB >16.5 bits is mandatory and power budget allows >10× increase; not drop-in due to pinout, drive, and timing differences. |
| ADS8860IDRCT | 1MSPS, 16-bit, pseudo-differential; 1.8V supply; 4.8mW at 1MSPS; no daisy-chain mode; max temp 85°C. | Optimized for ultra-low-voltage portable systems; lacks 125°C H-grade option and chain-mode synchronization. | Prefer for battery-powered handheld instruments where 1.8V IO compatibility is essential and 250ksps is sufficient. |
Compared with AD7960BCPZ and ADS8860IDRCT, the LTC2364CMS-16#TRPBF uniquely balances 250ksps speed, 16-bit accuracy, ultra-low 3.4mW power, and daisy-chain capability in a compact MSOP - making it optimal for space-constrained, thermally demanding, multi-channel embedded data acquisition.

FAQ
What is the maximum recommended reference voltage for LTC2364CMS-16#TRPBF?
The LTC2364CMS-16#TRPBF supports VREF from 2.5V to 5.1V per Absolute Maximum Ratings and Electrical Characteristics tables. Operation above 5.1V risks damage; 5.0V is commonly used to maximize SNR and maintain margin. The REF pin draws up to 0.2mA at 250ksps, so the reference source must sustain this load without droop exceeding 0.5LSB (e.g., <125µV at 5V).
Does LTC2364CMS-16#TRPBF require external clocking for conversion timing?
No - the LTC2364CMS-16#TRPBF integrates an internal oscillator that sets conversion time (tCONV = 1.9–3µs). External clocking is unnecessary for basic operation; only the SCK signal is needed for serial data readout. This eliminates timing jitter from external sources and simplifies system-level clock tree design.
Can LTC2364CMS-16#TRPBF operate with 1.8V digital I/O while using 2.5V analog supply?
Yes - the LTC2364CMS-16#TRPBF separates analog (VDD = 2.5V) and digital I/O (OVDD = 1.71V–5.25V) supplies. With OVDD = 1.8V, VIH = 1.44V and VIL = 0.36V are guaranteed, enabling direct interfacing to 1.8V FPGAs or microcontrollers without level shifters.
How does the pseudo-differential input architecture of LTC2364CMS-16#TRPBF improve noise immunity?
The LTC2364CMS-16#TRPBF accepts IN+ (0V to VREF) and IN– (±100mV around GND), rejecting common-mode noise coupled equally to both inputs. With 80dB CMRR at 125kHz, it suppresses interference from switching power supplies or motor drives - critical in industrial settings where ground loops and EMI degrade single-ended measurements.
Is LTC2364CMS-16#TRPBF pin-compatible with other variants like LTC2364IMS-16#TRPBF?
Yes - all LTC2364-16 MSOP variants (C/I/H grades) share identical 16-lead MSOP pinout and footprint. The LTC2364CMS-16#TRPBF (0°C to 70°C) can be substituted with LTC2364IMS-16#TRPBF (–40°C to 85°C) or LTC2364HMS-16#TRPBF (–40°C to 125°C) without PCB changes, provided thermal and reliability requirements align.
