Product details
Overview
LTC2286CUP#TRPBF from Analog Devices (formerly Linear Technology) is a dual 10-bit, 25Msps low-noise analog-to-digital converter operating from a single 3V supply. It delivers 61.8dB SNR and 85dB SFDR at Nyquist, with 110dB channel isolation at 100MHz and 575MHz full-power bandwidth. Designed for high-fidelity signal digitization in portable instrumentation and spectral analysis systems.
For engineers reviewing the LTC2286CUP#TRPBF datasheet, LTC2286CUP#TRPBF pinout, LTC2286CUP#TRPBF application, or LTC2286CUP#TRPBF equivalent, key selection criteria include its 25Msps sample rate, dual-channel 10-bit resolution, flexible ±0.5V to ±1V differential input range, clock duty cycle stabilizer, and 64-pin QFN package with exposed thermal pad.
Technical Context
The LTC2286CUP#TRPBF implements a six-stage CMOS pipelined ADC architecture with 5-cycle pipeline latency and integrated sample-and-hold. It supports independent or multiplexed digital output buses via MUX pin control and features separate analog (VDD) and digital output (OVDD) supplies for logic-level flexibility from 0.5V to 3.6V.
Its dual-channel design includes per-channel shutdown (SHDNA/SHDNB), output enable (OEA/OEB), overflow detection (OFA/OFB), and reference programming (SENSEA/SENSEB) pins. The internal 1.5V VCM bias and clock duty cycle stabilizer enable stable operation across wide input frequency ranges without external clock conditioning.
Key Specifications

Pinout & Package
64-lead (9mm × 9mm) plastic QFN package with exposed GND pad (Pin 65) requiring PCB soldering for thermal and electrical integrity. Package meets JEDEC MO-220 standard with θJA = 20°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AINA+/AINA–, AINB+/AINB– | Differential analog inputs (Ch A & B) | Accept ±0.5V to ±1V differential input range; require matched trace routing for optimal CMRR & harmonic performance. |

| SHDNA/SHDNB, OEA/OEB | Per-channel power and output control | Enable nap mode (15mW/channel) or shutdown (2mW/channel); allow selective channel disabling without reset. |
| SENSEA/SENSEB | Reference programming inputs | Select ±0.5V (tie to VCMA/VCMB), ±1V (tie to VDD), or custom range (external 0.5–1V) - configure input scaling without external resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Single 3V supply operation | Eliminates dual-supply design complexity while maintaining 61.8dB SNR - reduces BOM count and layout area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9233BCPZ-25 | 12-bit, 25Msps, single-channel only; requires external multiplexer for dual-signal capture. | Lacks native dual-channel architecture and channel isolation - unsuitable for simultaneous I/Q or correlated sampling. | Choose only if higher resolution (12-bit) is prioritized over dual-channel synchronization and isolation. |
| LTC2287CUP#TRPBF | Same family, 10-bit, 40Msps; 235mW power, identical pinout and feature set. | Higher sample rate enables wider instantaneous bandwidth (20MHz) but increases power and thermal load. | Select when system requires >12.5MHz real-time bandwidth and can accommodate +85mW power increase. |
Compared with AD9233BCPZ-25 and LTC2287CUP#TRPBF, the LTC2286CUP#TRPBF uniquely balances dual-channel synchronization, 110dB isolation, and ultra-low 150mW power at 25Msps - making it optimal for portable, battery-constrained, and phase-coherent measurement systems.

FAQ
What is the operating temperature range for the LTC2286CUP#TRPBF?
The LTC2286CUP#TRPBF is specified for commercial-grade operation from 0°C to +70°C ambient temperature. This range is confirmed in the Absolute Maximum Ratings table and applies to all DC and AC specifications unless otherwise noted. The 'C' suffix in LTC2286CUP#TRPBF explicitly denotes the commercial temperature grade, distinct from the industrial-grade 'I' variant (LTC2286IUP#TRPBF).
Does the LTC2286CUP#TRPBF support differential or single-ended analog inputs?
The LTC2286CUP#TRPBF supports both configurations. Its primary interface is fully differential (AINA+/AINA–, AINB+/AINB–), delivering optimal SNR and harmonic distortion. Single-ended operation is possible by grounding one input per channel, though this degrades THD by ~6dB and reduces common-mode rejection. The datasheet specifies performance metrics exclusively for differential drive, and design recommendations emphasize matched trace lengths and termination.
How does the MODE pin affect output format and clock stabilization on the LTC2286CUP#TRPBF?
The MODE pin on the LTC2286CUP#TRPBF selects both output coding and clock duty cycle stabilizer state. Ground sets offset binary format with stabilizer disabled; 1/3 VDD enables offset binary with stabilizer active; 2/3 VDD selects 2's complement with stabilizer active; VDD configures 2's complement with stabilizer off. This dual-function control simplifies board design by eliminating separate configuration lines while ensuring deterministic behavior across both channels simultaneously.
Can the LTC2286CUP#TRPBF drive 1.8V logic levels directly?
Yes, the LTC2286CUP#TRPBF can drive 1.8V logic directly via its OVDD supply pin. When OVDD is set to 1.8V, the digital outputs meet VOH ≥ 1.79V and VOL ≤ 0.09V under 1.6mA load, satisfying standard 1.8V CMOS input thresholds. This eliminates level-shifting circuitry when interfacing with modern FPGAs and low-voltage processors, reducing component count and signal integrity risk.
What is the purpose of the exposed pad (Pin 65) on the LTC2286CUP#TRPBF package?
The exposed pad (Pin 65) on the LTC2286CUP#TRPBF is electrically connected to GND and serves dual thermal and electrical functions. It must be soldered to a PCB copper pour tied to the system ground plane to achieve the specified θJA = 20°C/W thermal resistance and maintain signal integrity. Failure to connect this pad results in elevated junction temperature, degraded SNR, and potential long-term reliability issues due to thermal stress.
