Product details
Overview
LTC2364IMS-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 250ksps throughput with no pipeline latency, achieves ±0.75LSB INL max and 94.7dB SNR (typ), and is rated for –40°C to +85°C operation in 16-lead MSOP package - ideal for portable instrumentation and industrial process control.
For engineers reviewing the LTC2364IMS-16#TRPBF datasheet, LTC2364IMS-16#TRPBF pinout, LTC2364IMS-16#TRPBF application, or LTC2364IMS-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, daisy-chain SPI interface compatibility with 1.8V–5V logic, internal conversion clock, auto power-down at 3.4µW idle, and thermal stability up to 85°C.
Technical Context
The LTC2364IMS-16#TRPBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, sampling pseudo-differential inputs (IN+, IN–) during acquisition and executing binary-search conversion against VREF fractions. Its internal oscillator eliminates external clock dependency, and conversion timing is fixed at 1.9–3µs with no cycle latency.
It features dual-supply operation: 2.375–2.625V on VDD for analog core and 1.71–5.25V on OVDD for digital I/O, enabling interoperability with mixed-voltage host systems. The RDL/SDI pin functions as bus enable (CHAIN = low) or serial data input (CHAIN = high), supporting flexible daisy-chain configurations without additional control lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full 65,536-code dynamic range with monotonic transfer function and no missing codes across temperature. |
| Sampling Rate | 250ksps - enables real-time capture of signals up to 125kHz Nyquist bandwidth with deterministic timing. |
| SNR | 94.7dB (typ, fIN = 2kHz, VREF = 5V) - corresponds to effective resolution >15.5 bits and <76µV RMS noise floor at full scale. |
| INL | ±0.75LSB (max) - ensures linearity error ≤±0.00115% of full scale, critical for precision measurement accuracy. |
| Power Dissipation | 3.4mW at 250ksps - enables battery-powered operation with thermal budget under 50mW in MSOP package. |
| Reference Range | 2.5V to 5.1V - allows system-level scaling of input range while maintaining LSB size from 38µV (2.5V) to 77µV (5.1V). |
| Operating Temp | –40°C to +85°C - qualified for industrial environments without derating; H-grade variant extends to 125°C. |
Pinout & Package
Package: 16-lead plastic MSOP (3mm × 4.9mm), exposed pad not present (DFN variant has exposed GND pad; MSOP does not). Pin pitch: 0.65mm. Thermal resistance θJA = 110°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | High enables daisy-chain mode (RDL/SDI = SDI); low enables normal mode (RDL/SDI = bus enable). |
| VDD (2) | Analog supply | 2.5V ±62.5mV core supply; bypass with 10µF ceramic capacitor to GND for noise immunity. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce; connect all to common low-impedance plane. |
| IN+ (4) | Pseudo-differential input | Accepts 0V to VREF voltage relative to IN–; 45pF input capacitance requires low-Z drive for settling. |
| IN– (5) | Common-mode sense | Input range ±100mV w.r.t. GND; must be tied to ground plane or remote sense point for CMRR >80dB. |
| REF (7,8) | Reference input | Dual-pin connection for low-inductance decoupling; requires 47µF X5R ceramic (0805) close to pins. |
| CNV (9) | Convert trigger | Rising-edge initiated conversion; powers up ADC and starts acquisition phase with 20ns min pulse width. |
| BUSY (11) | Status indicator | Active-high open-drain output signaling conversion progress; asserts 13ns after CNV↑, deasserts at completion. |
| RDL/SDI (12) | Configurable I/O | In normal mode: bus enable for SDO tri-state; in chain mode: serial data input for daisy-chained ADCs. |
| SCK (13) | Serial clock | Accepts 10ns min period (100MHz max); rising edge clocks out MSB-first 16-bit straight-binary data on SDO. |
| SDO (14) | Serial output | Tri-stateable output driven by OVDD; data valid 9.5ns after SCK↑ (CL = 20pF); supports daisy-chain readback. |
| 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 - critical for closed-loop control and real-time triggering. |
| Auto power-down | Reduces current to 0.9µA between conversions; power scales linearly with sample rate, enabling 3.4µW at 250sps. |
| SPI-compatible daisy-chain | Single SCK/SDO path supports multi-ADC synchronization without additional chip-select lines or timing skew. |
| Internal conversion clock | Eliminates need for external timing circuitry; simplifies PCB layout and improves jitter immunity over external clock solutions. |
| Guaranteed 16-bit operation | Specified no-missing-codes and ±0.75LSB INL over full temperature range - validated for metrology-grade applications. |
| Wide VREF flexibility | 2.5V–5.1V reference range allows optimization of signal-to-noise ratio and input drive requirements per system design. |

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 |
|---|---|---|---|
| AD7682BCPZ-RL7 | 250ksps, 16-bit, pseudo-differential, but uses 5V VDD and lacks daisy-chain mode; INL ±1.5LSB (max). | Requires higher supply voltage and external clock; less suitable for low-voltage or multi-ADC synchronized systems. | Choose when legacy 5V system integration is required and daisy-chain is unnecessary. |
| ADS8860IDRCT | 16-bit, 1MSPS, single-ended input only; consumes 4.5mW at full speed; no internal oscillator - requires external clock. | Higher speed but sacrifices pseudo-differential input and autonomous timing; more complex clock tree design needed. | Prefer for bandwidth-critical applications where single-ended topology and external timing control are acceptable. |
Compared with AD7682BCPZ-RL7 and ADS8860IDRCT, the LTC2364IMS-16#TRPBF uniquely combines 2.5V operation, internal clock, daisy-chain support, and guaranteed ±0.75LSB INL - making it optimal for compact, thermally constrained, multi-channel industrial and portable systems demanding precision and simplicity.

FAQ
What is the maximum sampling frequency supported by the LTC2364IMS-16#TRPBF?
The LTC2364IMS-16#TRPBF supports a maximum sampling frequency of 250ksps across its full operating temperature range (–40°C to +85°C). This rate is guaranteed with no missing codes, ±0.75LSB INL, and 94.7dB SNR (typ) when VREF = 5V and fIN = 2kHz. Conversion time is fixed at 1.9–3µs, and inter-conversion interval is 4µs minimum.
Does the LTC2364IMS-16#TRPBF require an external clock source?
No, the LTC2364IMS-16#TRPBF integrates an internal oscillator that sets conversion timing autonomously. External clocking is unnecessary for basic operation. However, the SCK pin remains active for serial data transfer - it must be driven by the host processor to read results, but does not control conversion initiation or duration.
How does the daisy-chain mode work on the LTC2364IMS-16#TRPBF?
Daisy-chain mode is enabled by pulling the CHAIN pin high. In this mode, RDL/SDI becomes a serial data input, allowing multiple LTC2364IMS-16#TRPBF devices to share one SCK and SDO line. Each device shifts its 16-bit result into the next, enabling synchronized multi-channel capture with minimal GPIO usage and no inter-device timing skew.
What is the recommended reference voltage source for the LTC2364IMS-16#TRPBF?
The LTC6655-5 is explicitly recommended for the LTC2364IMS-16#TRPBF: a 5V, ultra-low-noise (0.25ppm p-p), low-drift (2ppm/°C) reference with fast settling. It maintains <0.5LSB deviation across the full code span at 250ksps and is fully specified over the H-grade temperature range - matching the LTC2364IMS-16#TRPBF's extended thermal envelope.
Can the LTC2364IMS-16#TRPBF operate with a 3.3V OVDD and 2.5V VDD simultaneously?
Yes - the LTC2364IMS-16#TRPBF is designed for dual-supply independence. VDD must be 2.375–2.625V (2.5V nominal) for analog core operation, while OVDD may range from 1.71V to 5.25V (including 3.3V) to interface with 3.3V logic. This separation prevents digital switching noise from coupling into the analog domain and ensures clean 16-bit performance.
