Product details
Overview
LTC2367CDE-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 500ksps throughput with no pipeline delay, achieves ±0.75LSB INL max and 94.7dB SNR (typ), and is housed in a 4mm × 3mm DFN package rated for 0°C to 70°C operation.
For engineers reviewing the LTC2367CDE-16#TRPBF datasheet, LTC2367CDE-16#TRPBF pinout, LTC2367CDE-16#TRPBF application, or LTC2367CDE-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 6.8µW idle, and thermal stability up to 70°C - all critical for portable instrumentation and medical imaging signal chains.
Technical Context
The LTC2367CDE-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 without latency. Its internal oscillator eliminates external clock dependency, and the CNV-triggered conversion sequence ensures deterministic timing with tCONV = 1.5µs max.
It features dual-supply operation: 2.5V analog core (VDD) and flexible I/O supply (OVDD = 1.71V–5.25V), enabling direct interfacing with 1.8V/2.5V/3.3V/5V host controllers. The REF input draws 0.24–0.32mA (typ) at 500ksps, requiring low-impedance decoupling via a 47µF X5R ceramic capacitor, while analog input capacitance is 45pF (sample mode) with 40Ω switch RON.

Pinout & Package
Package: 16-lead (4mm × 3mm) plastic DFN with exposed pad (Pin 17), RoHS-compliant, rated for 0°C to 70°C operation. Exposed pad must be soldered to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CHAIN (1) | Mode control input | Selects normal mode (RDL/SDI = bus enable) or daisy-chain mode (RDL/SDI = serial data input); referenced to OVDD. |
| VDD (2) | Analog supply | 2.5V ±62.5mV core supply; requires 10µF ceramic bypass to GND for noise suppression. |
| GND (3,6,10,16) | Ground reference | Four dedicated analog/digital ground pins minimize ground bounce and improve PSRR. |
| IN+ (4), IN– (5) | Pseudo-differential analog inputs | IN+ accepts 0V to VREF; IN– is ground-sense pin (±100mV range), enabling common-mode noise rejection. |
| REF (7,8) | Reference voltage input | Dual-pin connection for low-inductance 47µF X5R decoupling; defines full-scale range and LSB size (e.g., 76µV at 5V). |

| SCK (13), SDO (14) | SPI interface | MSB-first, SPI-compatible serial interface supporting 100MHz SCK; SDO tri-state controlled by RDL/SDI or CHAIN. |
| OVDD (15) | Digital I/O supply | 1.71V–5.25V logic interface supply; sets VIH/VIL thresholds and enables mixed-voltage system integration. |
| GND (17) | Exposed pad | Thermal and electrical ground connection; mandatory soldering required for thermal dissipation (θJA = 40°C/W). |
Key Features
| Feature | Design Value |

FAQ
What is the maximum sampling frequency supported by the LTC2367CDE-16#TRPBF?
The LTC2367CDE-16#TRPBF supports a maximum sampling frequency of 500ksps, with guaranteed timing parameters including tCYC = 2µs and tCONV = 1.5µs max. This enables full 16-bit conversion every 2 microseconds without pipeline delay or cycle latency, making it suitable for real-time signal acquisition in time-critical applications such as medical imaging and ATE.
Does the LTC2367CDE-16#TRPBF require an external clock source?
No, the LTC2367CDE-16#TRPBF integrates an internal oscillator that sets the conversion time, eliminating the need for an external clock source. This simplifies system design, reduces component count, and improves timing robustness - especially in noise-sensitive environments where external clock distribution could introduce jitter or EMI.
What reference voltage range is compatible with the LTC2367CDE-16#TRPBF?
The LTC2367CDE-16#TRPBF accepts a reference voltage (VREF) from 2.5V to 5.1V, applied to Pins 7 and 8. This wide range allows flexibility in system design - for example, using a 5V reference yields 76µV/LSB resolution, while a 2.5V reference halves LSB size to 38µV and maintains full 16-bit no-missing-codes performance.
How does the daisy-chain mode function on the LTC2367CDE-16#TRPBF?
In daisy-chain mode (CHAIN pin high), the LTC2367CDE-16#TRPBF accepts serial data on RDL/SDI and shifts out its own 16-bit result on SDO synchronized to SCK. Multiple devices can be cascaded so that one SCK edge clocks data through the entire chain - reducing microcontroller pin count and enabling synchronized multi-channel sampling without additional timing logic.
What is the power consumption of the LTC2367CDE-16#TRPBF at 500ksps and in shutdown mode?
At 500ksps, the LTC2367CDE-16#TRPBF consumes 6.8mW total (VDD + OVDD + IREF). In power-down mode, it draws only 0.9µA (typ), reducing power to 2.25µW - a >99.9% reduction ideal for duty-cycled systems like portable data loggers or wireless sensor nodes where acquisition occurs intermittently.
