Product details
Overview
LTC2364HMS-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 +125°C operation - ideal for industrial process control and high-reliability instrumentation.
For engineers reviewing the LTC2364HMS-16#TRPBF datasheet, LTC2364HMS-16#TRPBF pinout, LTC2364HMS-16#TRPBF application, or LTC2364HMS-16#TRPBF equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, H-grade temperature capability, SPI-compatible daisy-chain interface, internal conversion clock, and ultra-low 3.4mW power at full speed - all in a 16-lead MSOP package.
Technical Context
The LTC2364HMS-16#TRPBF employs a charge-redistribution CDAC architecture with pseudo-differential sampling, where IN+ accepts 0V to VREF signals while IN– serves as a ground-sense reference (±100mV range). Conversion is initiated by a rising edge on CNV, with BUSY signaling completion; an internal oscillator eliminates external clock dependency.
Its SPI-compatible serial interface supports 1.8V–5V logic levels via OVDD, enables daisy-chain mode via CHAIN/RDL/SDI, and outputs straight-binary 16-bit data MSB-first on SDO. Power scales dynamically: 3.4mW at 250ksps, 3.4µW at 250sps, with automatic power-down between conversions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-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 undersampling. |
| SNR | 94.7dB (typ, fIN = 2kHz, VREF = 5V) - supports >15.7 effective bits (ENOB) in precision measurement applications. |
| INL | ±0.75LSB (max, full temp range) - ensures linearity error remains below 1 LSB for accurate end-point calibration. |
| Power Consumption | 3.4mW at 250ksps (VDD = 2.5V) - enables battery-operated or thermally constrained designs without sacrificing speed. |
| Operating Temperature | –40°C to +125°C (H-grade) - qualified for under-hood automotive, downhole, and industrial control environments. |
| Reference Range | 2.5V to 5.1V - allows flexible scaling of input dynamic range while maintaining 76µV LSB size at 5V reference. |
Pinout & Package
Package: 16-lead plastic MSOP (5.0mm × 4.4mm), exposed pad not present (DFN variant has exposed pad; MSOP does not).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | Low = normal mode (RDL/SDI acts as bus enable); high = daisy-chain mode (RDL/SDI becomes serial data input). |
| VDD (2) | Analog supply | 2.5V ±62.5mV supply; powers core ADC and reference buffer; requires 10µF ceramic bypass to GND. |
| GND (3,6,10,16) | Analog/digital ground | Four dedicated GND pins minimize ground bounce and ensure stable reference and signal return paths. |
| IN+ (4) | Pseudo-differential analog input (+) | Accepts 0V to VREF unipolar signal; input capacitance = 45pF in sample mode; requires low-impedance drive. |
| IN– (5) | Pseudo-differential analog input (–) | Ground-sense pin with ±100mV range; must connect to system ground plane or remote sense point. |
| REF (7,8) | Reference voltage inputs | Dual-pin connection for 2.5V–5.1V external reference; requires 47µF X5R ceramic decoupling at pin. |
| CNV (9) | Convert trigger | Rising-edge–initiated conversion start; also powers up device from auto-power-down state. |
| BUSY (11) | Conversion status indicator | Active-high open-drain output; asserts high at CNV edge and deasserts when 16-bit result is ready. |
| RDL/SDI (12) | Serial I/O control / data input | Function depends on CHAIN state; in chain mode, receives MSB-first 16-bit data from upstream ADC. |
| SCK (13) | Serial clock input | Accepts 10ns min pulse width (up to 100MHz); controls timing of SDO data output and SDI sampling. |
| SDO (14) | Serial data output | MSB-first straight-binary 16-bit result; valid within 9.5ns after SCK↑; compatible with 1.8V–5V host logic. |
| OVDD (15) | I/O supply voltage | 1.71V–5.25V digital interface supply; sets logic thresholds for all digital pins; bypass with 0.1µF ceramic. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay or cycle latency | Enables deterministic timing for closed-loop control systems - conversion completes in fixed 1.9–3µs, with immediate BUSY deassertion. |
| Guaranteed 16-bit no missing codes | Valid across full –40°C to +125°C range and all supply/reference conditions - eliminates code gaps in critical safety monitoring. |
| Internal conversion clock | Removes need for external timing circuitry or clock distribution network - simplifies PCB layout and reduces BOM count. |
| Auto power-down between conversions | Reduces average power proportionally to sampling rate - e.g., drops to 3.4µW at 250sps, extending battery life in portable instruments. |
| SPI-compatible daisy-chain mode | Allows synchronous multi-channel acquisition using single SCK/SDO lines - cuts interconnect count and routing complexity in DAQ systems. |

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-RL7 | 18-bit, 5MSPS, differential input, requires external reference and driver; consumes 39mW at full speed. | Higher resolution/speed but significantly higher power and board area; needs precision op-amp and reference design. | Select when >16-bit ENOB and >1MSPS are required; avoid if thermal budget or layout space is constrained. |
| ADS8860IDRCT | 16-bit, 1MSPS, pseudo-differential, 2.5V supply, 1.5mW at 100ksps; rated only to 85°C (I-grade). | Lacks H-grade temperature rating and daisy-chain support; lower SNR (92dB) and higher INL (±1.25LSB). | Use for cost-sensitive, non-extended-temp applications where 1MSPS is needed and 125°C operation is unnecessary. |
Compared with AD7960BCPZ-RL7 and ADS8860IDRCT, the LTC2364HMS-16#TRPBF uniquely balances 250ksps speed, 125°C operation, 3.4mW power, and integrated daisy-chain capability - making it optimal for ruggedized, multi-channel, thermally demanding embedded DAQ systems.

FAQ
What is the maximum operating temperature of the LTC2364HMS-16#TRPBF?
The LTC2364HMS-16#TRPBF is an H-grade device rated for continuous operation from –40°C to +125°C. This specification is guaranteed across all electrical parameters in the datasheet, including INL, SNR, and power consumption - making it suitable for under-hood automotive, industrial motor drives, and aerospace applications where ambient temperatures exceed 105°C.
Does the LTC2364HMS-16#TRPBF require an external clock source?
No, the LTC2364HMS-16#TRPBF features an internal oscillator that sets conversion timing, eliminating the need for an external clock. The SCK pin is used solely for serial data transfer timing and supports frequencies up to 100MHz. This simplifies system design by removing clock distribution, jitter management, and synchronization overhead associated with external timing sources.
Can the LTC2364HMS-16#TRPBF interface directly with a 1.8V microcontroller?
Yes, the LTC2364HMS-16#TRPBF supports 1.8V logic levels via its OVDD pin, which accepts 1.71V to 5.25V. When OVDD = 1.8V, all digital inputs (CNV, SCK, CHAIN, RDL/SDI) recognize 0.2×OVDD (0.36V) as logic low and 0.8×OVDD (1.44V) as logic high, and SDO outputs are compatible with 1.8V CMOS receivers - enabling direct connection to low-voltage MCUs without level shifters.
What is the purpose of the dual REF pins (7 and 8) on the LTC2364HMS-16#TRPBF?
The dual REF pins (7 and 8) provide low-inductance, parallel connection points for the external reference voltage (2.5V–5.1V), minimizing impedance and voltage drop during high-current charge injection events at each conversion. Both pins must be connected to the same reference source and decoupled together with a single 47µF X5R ceramic capacitor placed as close as possible to the package - ensuring stable reference voltage and optimal SNR performance.
How does the daisy-chain mode work on the LTC2364HMS-16#TRPBF?
In daisy-chain mode (CHAIN = high), the LTC2364HMS-16#TRPBF accepts serial data on RDL/SDI and shifts out its own 16-bit result on SDO synchronously with SCK. Multiple devices can be cascaded: the SDO of one feeds RDL/SDI of the next, with BUSY and CNV shared. This enables synchronized multi-channel sampling using only three wires (SCK, CNV, BUSY), reducing interconnect complexity in high-channel-count DAQ systems.
