Product details
Overview
LTC2286IUP#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 supports flexible ±0.5V to ±1V differential input ranges. It is used in portable instrumentation and spectral analysis systems requiring high dynamic range digitization of wideband signals.
For engineers reviewing the LTC2286IUP#TRPBF datasheet, LTC2286IUP#TRPBF pinout, LTC2286IUP#TRPBF application, or LTC2286IUP#TRPBF equivalent, key selection criteria include its 25Msps sample rate, 64-pin QFN package, dual-channel isolation, clock duty cycle stabilizer, and support for multiplexed or separate digital output buses.
Technical Context
The LTC2286IUP#TRPBF implements a six-stage CMOS pipelined ADC architecture per channel, achieving 5-cycle pipeline latency and 575MHz full-power bandwidth. Its internal 1.5V reference buffer (VCMA/VCMB), programmable SENSEA/SENSEB inputs, and MODE-selectable offset binary/2's complement output format enable precise analog front-end configuration.
It features independent shutdown (SHDNA/SHDNB) and output enable (OEA/OEB) controls per channel, plus a shared clock duty cycle stabilizer and multiplexer (MUX) for bus sharing. Crosstalk is specified at –110dB at Nyquist, confirming robust inter-channel separation under high-frequency operation.
Key Specifications

Package: 64-lead (9mm × 9mm) plastic QFN with exposed GND pad (Pin 65), rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AINA+, AINA– | Channel A differential analog input | Accepts ±0.5V to ±1V differential signal; requires matched PCB routing for optimal CMRR. |

| SHDNA, SHDNB | Per-channel shutdown control | Combines with OEA/OEB to select normal, nap (15mW/channel), or sleep (2mW/channel) power states. |
| SENSEA, SENSEB | Reference programming inputs | Set input range: VCMA/VCMB → ±0.5V; VDD → ±1V; external voltage → ±VSENSE. |
| MODE (Pin 60) | Output format & stabilizer control | GND = offset binary + stabilizer off; 1/3 VDD = offset binary + stabilizer on; VDD = 2's complement + stabilizer off. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2287IUP#TRPBF | Higher 40Msps sample rate; 235mW power; identical 10-bit resolution and QFN-64 package. | Required for wider instantaneous bandwidth (e.g., 20MHz+ IF signals) where 25Msps is insufficient. | Select when system demands >25Msps sustained sampling without sacrificing SNR/SFDR or thermal envelope. |
| AD9236BCPZ-20 | Single-channel 12-bit, 20Msps; 3.3V supply; 48-lead LFCSP; 69dB SNR, 85dB SFDR. | Lower resolution but higher precision per channel; no dual-channel integration or MUX capability. | Choose for cost-sensitive, single-path applications needing 12-bit depth at ≤20Msps, accepting loss of channel pairing and bus flexibility. |
Compared with LTC2287IUP#TRPBF, the LTC2286IUP#TRPBF trades 15Msps bandwidth and 85mW power for tighter thermal management and lower system clocking complexity; versus AD9236BCPZ-20, it provides integrated dual-channel synchronization and bus multiplexing at the expense of 2-bit resolution.

FAQ
What is the guaranteed operating temperature range for the LTC2286IUP#TRPBF?
The LTC2286IUP#TRPBF is specified for industrial temperature operation from –40°C to +85°C. This rating applies to all DC and AC specifications marked with the ● symbol in the datasheet, including INL, DNL, SNR, SFDR, and channel isolation, ensuring consistent performance across the full range without derating.
Does the LTC2286IUP#TRPBF support external reference operation?
Yes, the LTC2286IUP#TRPBF supports external reference operation via REFHA/REFLA and REFLB/REFHB pins. When an external reference voltage between 0.5V and 1V is applied to SENSEA or SENSEB, the input range becomes ±VSENSE. Full-scale gain error is ±2.5%FS with external reference, and gain matching between channels is ±0.3%FS.
How does the MUX pin affect data output timing on the LTC2286IUP#TRPBF?
When MUX = HIGH on the LTC2286IUP#TRPBF, Channel A data appears on DA0–DA9 and OFA, while Channel B appears on DB0–DB9 and OFB. When MUX = LOW, the buses are swapped. In multiplexed mode (CLKA = CLKB = MUX), both channels share one bus with alternating samples, introducing tMD delay (1.4–5.4ns) instead of tD - verified in Figure TD02 of the datasheet.
What power savings are achieved in nap mode for the LTC2286IUP#TRPBF?
In nap mode (SHDNA = SHDNB = VDD, OEA = OEB = GND), the LTC2286IUP#TRPBF reduces power to 15mW per channel (30mW total), compared to 150mW in active operation. The analog core remains powered and ready for immediate resumption, with only digital output drivers disabled - ideal for burst-mode acquisition systems.
Can the LTC2286IUP#TRPBF drive 1.8V logic directly?
Yes, the LTC2286IUP#TRPBF supports 1.8V OVDD operation. With OVDD = 1.8V, VOH is guaranteed ≥1.79V at –200µA sink current and VOL ≤0.09V at 1.6mA source current, meeting standard 1.8V CMOS logic thresholds. Output drivers are independently biased by OVDD, decoupled from the 3V analog supply.
