Product details
Overview
LTC2288IUP#PBF from Analog Devices (formerly Linear Technology) is a dual 10-bit, 65Msps low-noise analog-to-digital converter operating from a single 3V supply (2.7V–3.4V), delivering 61.8dB SNR and 85dB SFDR at Nyquist, with 110dB channel isolation at 100MHz. It targets high-fidelity digitization in broadband communications receivers and medical ultrasound imaging systems.
For engineers reviewing the LTC2288IUP#PBF datasheet, LTC2288IUP#PBF pinout, LTC2288IUP#PBF application, or LTC2288IUP#PBF equivalent, key selection criteria include its dual-channel pipelined architecture, flexible ±0.5V to ±1V differential input range, clock duty cycle stabilizer, and multiplexed/parallel digital output bus configuration.
Technical Context
The LTC2288IUP#PBF implements a six-stage CMOS pipelined ADC architecture per channel, with 5-cycle pipeline latency and aperture jitter of 0.2psRMS. It supports independent or synchronized sampling via separate CLKA/CLKB inputs and includes on-chip 1.5V VCM bias generators for both channels.
Its dual-reference structure-separate REFHA/REFLA and REFHB/REFLB pairs-enables independent gain and offset calibration per channel. The MODE pin selects between offset binary or 2's complement output format and enables/disables the clock duty cycle stabilizer, while SENSEA/SENSEB pins configure input full-scale range using internal or external references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit with no missing codes - guarantees monotonic transfer function for precision measurement applications. |
| Sampling Rate | 65Msps - supports real-time digitization of IF signals up to 32.5MHz without undersampling constraints. |
| SNR @ 5MHz | 61.8dBFS - enables >10 effective bits of dynamic resolution for baseband signal capture. |
| SFDR @ 5MHz | 85dBc - suppresses spurious tones critical for spectral analysis and adjacent-channel interference rejection. |
| Channel Isolation | –110dB at 100MHz - prevents crosstalk-induced distortion in time-interleaved or dual-path receiver architectures. |
| Power Dissipation | 400mW at 65Msps - balances performance and thermal load in space-constrained RF front-ends. |
| Input Bandwidth | 575MHz full-power - preserves fidelity of wideband modulated signals without external anti-alias filtering. |
Pinout & Package
64-pin (9mm × 9mm) plastic QFN package with exposed thermal pad (Pin 65 = GND), rated for –40°C to +85°C operation. Requires soldering of exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AINA+, AINA– | Channel A differential analog input | Accepts ±0.5V to ±1V differential signal; requires matched trace routing and termination for optimal AC performance. |
| CLKA, CLKB | Independent sampling clock inputs | Positive-edge triggered; supports asynchronous or phase-aligned dual-channel sampling. |
| DA0–DA9, DB0–DB9 | Parallel digital outputs (10-bit each) | Configurable as separate buses or multiplexed via MUX pin; OVDD supports 0.5V–3.6V logic interfacing. |
| SHDNA, SHDNB | Per-channel shutdown control | Enables independent power gating: nap mode (15mW/channel) or shutdown (2mW/channel). |
| MODE | Output format & duty cycle stabilizer control | Selects offset binary/2's complement and enables clock jitter correction for non-50% duty cycles. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent ADC cores | Enables simultaneous sampling of I/Q or dual-band signals without time skew or inter-channel delay mismatch. |
| Flexible input range programming | SENSEA/SENSEB pins allow ±0.5V, ±1V, or user-defined ±VSENSE ranges-eliminates external gain stages in multi-signal-level systems. |
| Integrated clock duty cycle stabilizer | Compensates for clock source asymmetry, maintaining full 61.8dB SNR even with 40%–60% duty cycle clocks. |
| Per-channel power management | Independent SHDN/OE control per channel allows dynamic power scaling-e.g., disable Channel B during single-channel burst mode. |
| On-chip 1.5V common-mode bias | VCMA/VCMB outputs reduce external component count for differential driver interface and simplify PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9236BCPZ-65 | Single 12-bit, 65Msps ADC; no dual-channel integration; higher 70.5dB SNR but no channel isolation spec. | Requires two devices and precise clock/data alignment for dual-channel use; lacks integrated MUX and per-channel shutdown. | Choose when 12-bit resolution outweighs dual-channel integration and power efficiency. |
| LTC2287IUP#PBF | Same family, 10-bit, 40Msps variant; lower 235mW power; identical pinout and feature set except reduced sample rate. | Direct drop-in replacement where 40Msps suffices; retains all interface compatibility and thermal profile. | Choose for cost-sensitive or lower-bandwidth applications where 65Msps headroom is unnecessary. |

FAQ
What is the operating temperature range for the LTC2288IUP#PBF?
The LTC2288IUP#PBF is specified for industrial operation from –40°C to +85°C, as indicated by the "I" grade suffix in the part number. This range is validated across all key AC and DC specifications including SNR, SFDR, INL, and DNL, making it suitable for deployment in outdoor base stations and portable diagnostic equipment.
Does the LTC2288IUP#PBF support differential clock inputs?
No, the LTC2288IUP#PBF accepts only single-ended clock inputs on CLKA and CLKB pins. However, its integrated clock duty cycle stabilizer compensates for non-50% duty cycle clocks, enabling robust operation with standard CMOS or LVCMOS clock sources without requiring external duty cycle correction circuitry.
How is input full-scale range configured on the LTC2288IUP#PBF?
Input full-scale range on the LTC2288IUP#PBF is set per channel via SENSEA (Channel A) and SENSEB (Channel B) pins: connecting to VCMA/VCMB selects ±0.5V, to VDD selects ±1V, or applying an external voltage between 0.5V and 1V selects ±VSENSE. This eliminates need for external reference buffers or gain-switching components.
Can the LTC2288IUP#PBF operate with separate analog and digital supplies?
Yes-the LTC2288IUP#PBF uses VDD (2.7V–3.4V) for analog circuitry and OVDD (0.5V–3.6V) for digital output drivers, allowing direct interface to 1.8V, 2.5V, or 3.3V logic families without level shifters. OGND and GND must be tied together at a single point near the device.
What is the significance of the exposed pad (Pin 65) on the LTC2288IUP#PBF?
The exposed pad (Pin 65) on the LTC2288IUP#PBF is electrically and thermally connected to GND. It must be soldered to a solid PCB ground plane to ensure proper thermal dissipation (θJA = 20°C/W) and minimize ground bounce noise that could degrade SNR and SFDR performance.
