Product details
Overview
LTC2367HMS-16#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit pseudo-differential unipolar successive approximation register (SAR) ADC with 500ksps throughput, ±0.75LSB INL max, 94.7dB SNR (typ), and operation up to 125°C. It operates from a single 2.5V supply, accepts VREF from 2.5V to 5.1V, and delivers no missing codes at full resolution-ideal for high-speed, low-power precision data acquisition in harsh environments.
For engineers reviewing the LTC2367HMS-16#TRPBF datasheet, LTC2367HMS-16#TRPBF pinout, LTC2367HMS-16#TRPBF application, or LTC2367HMS-16#TRPBF equivalent, key selection criteria include guaranteed H-grade temperature operation (–40°C to 125°C), SPI-compatible daisy-chain interface, internal conversion clock, zero-cycle latency, and 6.8mW power consumption at full speed.
Technical Context
The LTC2367HMS-16#TRPBF employs a charge-redistribution capacitor DAC architecture with differential comparator, enabling true 16-bit linearity without missing codes. Its pseudo-differential input structure (IN+, IN–) supports common-mode rejection while maintaining unipolar 0V to VREF range, with IN– limited to ±100mV relative to GND.
Conversion is initiated by a rising edge on CNV; an internal oscillator eliminates external clock dependency. The device features automatic power-down between conversions, scaling quiescent current to sampling rate-6.8µW at 500sps-and supports 1.8V–5V I/O logic via dedicated OVDD supply independent of analog VDD.
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 | 500ksps-enables real-time capture of signals up to 250kHz Nyquist bandwidth with zero pipeline delay. |
| SNR | 94.7dB (typ) at fIN = 2kHz, VREF = 5V-defines minimum detectable signal above noise floor in high-fidelity applications. |
| INL | ±0.75LSB (max) over full temperature range-ensures end-point linearity critical for calibration-sensitive systems. |
| Power Dissipation | 6.8mW at 500ksps-achieved with 2.5V VDD and 2.5V OVDD, enabling battery-operated instrumentation. |
| Operating Temperature | –40°C to +125°C (H-grade)-validated for industrial process control and automotive under-hood sensing. |
| Reference Range | VREF = 2.5V to 5.1V-supports flexible full-scale adjustment while maintaining 76µV LSB size at 5V reference. |
Pinout & Package
Package: 16-lead plastic MSOP (H-grade, –40°C to 125°C). Exposed pad not present in MSOP variant; thermal performance θJA = 110°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | High enables daisy-chain SPI mode; low configures RDL/SDI as bus enable for standalone operation. |
| VDD (2) | Analog supply | 2.5V ±62.5mV supply powering core ADC and reference buffer; requires 10µF ceramic bypass to GND. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce and improve PSRR in high-speed sampling. |
| IN+ (4) | Positive analog input | Pseudo-differential input with 0V to VREF range; sees 45pF capacitance and 40Ω switch resistance during acquisition. |
| IN– (5) | Common-mode sense | Accepts ±100mV relative to GND; must be tied to system ground or remote ground plane for CMRR optimization. |
| REF (7,8) | Reference input | Dual-pin connection for low-impedance 2.5V–5.1V reference; requires 47µF X5R ceramic decoupling at package. |
| CNV (9) | Convert trigger | Rising-edge–sensitive input initiating acquisition and conversion; no minimum pulse width required beyond 20ns high time. |
| BUSY (11) | Status indicator | Open-drain output active high during conversion; asserts within 13ns of CNV↑ and clears after 1.5µs conversion time. |
| RDL/SDI (12) | Serial interface control/data | Function depends on CHAIN state: bus enable (low) or serial data input (high) for multi-device chains. |
| SCK (13) | Serial clock | Accepts 10ns min period (100MHz max), synchronous to SDO output; timing valid across 1.8V–5V OVDD range. |
| SDO (14) | Serial data output | MSB-first straight-binary output; data valid 9.5ns after SCK↑ with 20pF load; tri-stated when RDL/SDI = low. |
| OVDD (15) | I/O supply | 1.71V–5.25V digital interface supply-decouples logic voltage from analog domain and enables mixed-voltage system interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| No cycle latency | Immediate data availability after BUSY↓-eliminates FIFO buffering and simplifies real-time control loop design. |
| Auto power-down | Reduces current to 0.9µA (H-grade) between conversions-critical for burst-mode portable instrumentation. |
| SPI-compatible daisy-chain | Enables synchronized sampling across multiple LTC2367HMS-16#TRPBF devices using single SCK/SCKCH and shared CNV. |
| Guaranteed H-grade operation | Full AC/DC specifications validated from –40°C to +125°C-no derating required for extended-temperature industrial deployment. |
| Internal conversion clock | Removes need for external timing circuitry-reduces BOM count and layout sensitivity in space-constrained designs. |

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 |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1MSPS, 2.5V supply, but only rated to 85°C (I-grade); SNR = 92.5dB typ; no daisy-chain mode. | Not qualified for 125°C operation; lacks chain mode for multi-ADC synchronization; higher power (11mW at 1MSPS). | Select when higher speed (1MSPS) is mandatory and temperature range is limited to –40°C to 85°C. |
| AD7960BCPZ-RL7 | 18-bit, 5MSPS, 5V supply, –40°C to 85°C; requires external reference and separate analog/digital supplies; no integrated oscillator. | Higher resolution and speed but demands complex power sequencing, external clock, and reference design; larger 40-lead LFCSP package. | Select when 18-bit resolution and 5MSPS throughput justify added layout complexity and thermal derating. |
Compared with ADS8860IDRCT and AD7960BCPZ-RL7, the LTC2367HMS-16#TRPBF uniquely combines H-grade temperature qualification, internal clock, daisy-chain capability, and ultra-low 6.8mW power at 500ksps-making it optimal for ruggedized, space-constrained, multi-channel precision acquisition where thermal robustness and system integration simplicity are prioritized over raw speed or bit depth.

FAQ
What is the maximum operating temperature specification for the LTC2367HMS-16#TRPBF?
The LTC2367HMS-16#TRPBF is an H-grade device with a guaranteed operating temperature range of –40°C to +125°C. All electrical specifications-including INL, SNR, and THD-are tested and warranted across this full range, unlike C- or I-grade variants which are limited to 70°C or 85°C maximum.
Does the LTC2367HMS-16#TRPBF require an external clock source for conversion timing?
No, the LTC2367HMS-16#TRPBF integrates an internal oscillator that sets conversion time (tCONV = 1.5µs typ). This eliminates dependency on external clock generation, simplifying PCB layout and reducing jitter sensitivity-though an external SCK is still required for serial data readout.
How does the pseudo-differential input architecture of the LTC2367HMS-16#TRPBF differ from fully differential inputs?
The LTC2367HMS-16#TRPBF accepts a pseudo-differential input: IN+ swings 0V to VREF, while IN– is restricted to ±100mV around GND and serves as common-mode reference. This differs from true differential inputs (e.g., ±VREF) and enables unipolar signal acquisition with inherent common-mode noise rejection without requiring matched complementary signal paths.
Can the LTC2367HMS-16#TRPBF interface directly with a 1.8V microcontroller SPI port?
Yes-the LTC2367HMS-16#TRPBF supports 1.8V to 5V logic levels via its dedicated OVDD supply pin. When OVDD = 1.8V, VIH = 1.44V min and VIL = 0.36V max, ensuring reliable communication with 1.8V FPGA or MCU SPI peripherals without level-shifting circuitry.
What is the purpose of the CHAIN pin on the LTC2367HMS-16#TRPBF, and how does it affect SPI operation?
The CHAIN pin configures the serial interface mode: when low, RDL/SDI acts as a bus-enable input for standalone operation; when high, RDL/SDI becomes SDI for daisy-chain mode-allowing multiple LTC2367HMS-16#TRPBF devices to share one SCK and CNV while shifting out results sequentially on a single SDO line.
