Product details
Overview
LTC2367IMS-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 from a single 2.5V supply. It supports VREF from 2.5V to 5.1V and delivers no missing codes at full resolution-ideal for high-speed, low-power data acquisition in portable instrumentation and industrial control.
For engineers reviewing the LTC2367IMS-16#TRPBF datasheet, LTC2367IMS-16#TRPBF pinout, LTC2367IMS-16#TRPBF application, or LTC2367IMS-16#TRPBF equivalent, key selection considerations include guaranteed 16-bit linearity over –40°C to 85°C, SPI-compatible daisy-chain interface with 1.8V–5V I/O support, internal conversion clock, and auto power-down scaling from 6.8mW (500ksps) to 6.8µW (500sps).
Technical Context
The LTC2367IMS-16#TRPBF implements a charge-redistribution SAR architecture with a 16-bit CDAC and differential comparator, sampling the IN+/IN– pseudo-differential input during acquisition and executing binary-search conversion without pipeline latency. Its internal oscillator eliminates external timing dependencies, and the CNV-triggered conversion sequence ensures deterministic 2µs cycle time.
It features dual-supply operation: 2.5V (VDD) for analog core and programmable OVDD (1.71V–5.25V) for digital I/O, enabling direct interfacing with 1.8V, 2.5V, 3.3V, or 5V host controllers. The CHAIN pin enables daisy-chain mode for multi-ADC synchronization, while RDL/SDI reconfigures as serial data input in that mode.
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. |
| 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 ≤0.0011% full-scale error across temperature (–40°C to 85°C). |
| Power Consumption | 6.8mW at 500ksps - enables battery-operated systems with <14µA average current per sample. |
| Reference Range | VREF = 2.5V to 5.1V - allows flexible input scaling; LSB = 76µV at 5V reference. |
| THD | –119dB (typ, fIN = 2kHz) - supports high-fidelity signal reconstruction with minimal harmonic contamination. |
Pinout & Package
Package: 16-lead plastic MSOP (small-outline package), rated for –40°C to +85°C operating temperature. Exposed pad not present (MSOP variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode selector | Low = normal mode (RDL/SDI = bus enable); high = daisy-chain mode (RDL/SDI = serial data input). |
| VDD (2) | Analog supply | 2.5V ±62.5mV core supply; bypass with 10µF ceramic capacitor to GND. |
| GND (3,6,10,16) | Ground reference | Four dedicated ground pins minimize ground bounce and improve PSRR. |
| IN+ (4) | Pseudo-differential input | Accepts 0V to VREF relative to IN–; 45pF input capacitance in sample mode. |
| IN– (5) | Common-mode sense | ±100mV range w.r.t. GND; ties to system ground or remote sense point for CMRR optimization. |
| REF (7,8) | Reference input | Dual-pin connection for low-impedance decoupling; requires 47µF X5R ceramic (0805) close to pins. |
| CNV (9) | Conversion trigger | Rising edge initiates acquisition and conversion; minimum 20ns pulse width required. |
| BUSY (11) | Status indicator | Active-high open-drain output signaling conversion in progress (tBUSYLH = 13ns). |
| RDL/SDI (12) | Configurable I/O | Bus enable (CHAIN = low) or serial data input (CHAIN = high); 5V-tolerant when OVDD ≤ 5.25V. |
| SCK (13) | Serial clock | Supports up to 100MHz SCK (10ns period); rising-edge sampled for SDI, MSB-first output on SDO. |
| SDO (14) | Serial data output | 3-state output driven by OVDD; outputs 16-bit straight-binary code after BUSY goes low. |
| OVDD (15) | Digital I/O supply | 1.71V–5.25V logic interface supply; sets VIH/VIL thresholds and output drive strength. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay or cycle latency | Enables deterministic real-time control loops with 2µs total conversion-to-data-readout time. |

| Pseudo-differential unipolar input architecture | Rejects common-mode noise up to 80dB at 250kHz while supporting 0V–VREF input range without bipolar supply. |

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 requires external reference and has higher 11.5mW power at full speed. | Higher speed suits wider bandwidth test systems; lacks integrated daisy-chain mode and auto power-down. | Select when >500ksps sampling or tighter aperture jitter (<2ps) is required; verify external reference stability and layout for THD compliance. |
| AD7960BCPZ-RL7 | 18-bit, 5MSPS, pseudo-differential, but uses LVDS interface and requires ±2.5V supplies plus external reference. | Targeted at high-end instrumentation; incompatible pinout, higher BOM cost, and complex power sequencing. | Choose only when 18-bit resolution and >1MSPS throughput justify added complexity and cost; not drop-in compatible. |
Compared with ADS8860IDRCT and AD7960BCPZ-RL7, the LTC2367IMS-16#TRPBF offers optimal balance of 16-bit accuracy, 500ksps throughput, ultra-low power scalability, and simplified SPI interface with built-in daisy-chain capability-making it ideal for space-constrained, battery-aware, and multi-channel embedded systems.

FAQ
What is the operating temperature range for the LTC2367IMS-16#TRPBF?
The LTC2367IMS-16#TRPBF is rated for –40°C to +85°C (I-grade), with all key specifications-including ±0.75LSB INL max, 94.7dB SNR typ, and 500ksps throughput-guaranteed across this full range. This makes LTC2367IMS-16#TRPBF suitable for industrial and extended-environment deployments where ambient temperatures exceed commercial grade limits.
Does the LTC2367IMS-16#TRPBF require an external reference voltage?
Yes, the LTC2367IMS-16#TRPBF requires an external reference applied to its REF pins (7 and 8). It accepts VREF from 2.5V to 5.1V, and performance metrics like SNR and THD are specified at 5V reference. For optimal results, use a low-noise, low-drift reference such as the LTC6655-5, decoupled with a 47µF X5R ceramic capacitor placed directly at the REF pins.
How does the daisy-chain mode work on the LTC2367IMS-16#TRPBF?
In daisy-chain mode (CHAIN pin = high), the LTC2367IMS-16#TRPBF configures RDL/SDI as a serial data input, allowing cascaded SDO-to-SDI connections across multiple devices. A single SCK line clocks data out from the last device in the chain, enabling synchronized multi-channel sampling with minimal GPIO usage-critical for compact, high-channel-count data acquisition systems using LTC2367IMS-16#TRPBF.
What is the minimum CNV pulse width required for reliable operation of the LTC2367IMS-16#TRPBF?
The LTC2367IMS-16#TRPBF requires a minimum CNV high time (tCNVH) of 20ns, verified across all OVDD supply voltages (1.71V, 2.5V, and 5.25V). This specification ensures proper initialization of the internal sampling switch and CDAC array. Shorter pulses may result in incomplete acquisition or conversion errors-designers must ensure controller-generated CNV edges meet this timing requirement for every LTC2367IMS-16#TRPBF instance.
Can the LTC2367IMS-16#TRPBF operate with different OVDD and VDD supply voltages?
Yes-the LTC2367IMS-16#TRPBF supports independent supplies: VDD = 2.375V–2.625V (2.5V nominal) powers the analog core, while OVDD = 1.71V–5.25V powers the digital I/O interface. This allows direct interfacing with 1.8V, 2.5V, 3.3V, or 5V host processors without level shifters. However, OVDD must remain within absolute maximum ratings (≤6V), and both supplies must be stable before initiating CNV pulses.
