Product details
Overview
LTC2283CUP#TRPBF from Analog Devices (formerly Linear Technology) is a dual 12-bit, 125 Msps low-power 3V analog-to-digital converter optimized for high-frequency, wide-dynamic-range signal digitization in communications and imaging systems. It delivers 70.2 dB SNR and 88 dB SFDR at 5 MHz input, supports ±0.5 V to ±1 V differential input range, and operates from a single 2.85–3.4 V supply with 790 mW total power dissipation.
For engineers reviewing the LTC2283CUP#TRPBF datasheet, LTC2283CUP#TRPBF pinout, LTC2283CUP#TRPBF application, or LTC2283CUP#TRPBF equivalent, key selection criteria include dual-channel interleaving capability, 640 MHz full-power bandwidth, channel isolation of –110 dB at 100 MHz, clock duty cycle stabilizer support, and flexible output voltage drive (0.5–3.6 V).
Technical Context
The LTC2283CUP#TRPBF implements a six-stage CMOS pipelined ADC architecture per channel, achieving 5-cycle pipeline latency and supporting simultaneous sampling via independent CLKA/CLKB inputs or synchronized operation when tied together. Its sample-and-hold features 0.2 ps RMS aperture jitter and 3.5 pF sampling capacitance, enabling accurate high-frequency acquisition up to Nyquist.
It integrates dual independent reference paths with programmable input ranges via SENSEA/SENSEB pins, internal 1.5 V common-mode bias (VCMA/VCMB), and configurable output formats (offset binary or 2's complement) controlled by the MODE pin. The CLKOUT output provides a data-ready strobe derived from CLKB with <0.6 ns skew relative to data.
Key Specifications

| Sample Rate | 125 Msps maximum - enables digitization of signals up to 62.5 MHz baseband bandwidth per Nyquist criterion. |
| SNR @ 5 MHz | 70.2 dBFS - determines minimum detectable signal level in noise-limited receivers and spectral analyzers. |
| SFDR @ 5 MHz | 88 dBc - defines spurious-free dynamic range for multi-tone communication signals like LTE or DOCSIS. |
| Channel Isolation | –110 dB at 100 MHz - ensures minimal crosstalk between channels during simultaneous wideband acquisition. |
| Power Dissipation | 790 mW at 125 Msps - enables thermal management in compact, air-cooled instrumentation and portable radios. |

Pinout & Package
Package: 64-lead (9 mm × 9 mm) plastic QFN with exposed ground pad (Pin 65), RoHS-compliant lead-free finish, rated for 0°C to 70°C operating temperature (C-grade).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AINA+, AINA– | Differential analog input Channel A | Accepts ±0.5 V to ±1 V differential signal; requires matched 100 Ω source impedance for optimal SFDR. |
| AINB+, AINB– | Differential analog input Channel B | Independent second channel with identical AC performance and biasing requirements as Channel A. |
| CLKA, CLKB | Sampling clock inputs | Single-ended TTL/CMOS-compatible; rising edge initiates sampling; can be tied for synchronous dual-channel capture. |
| DA0–DA11, DB0–DB11 | Parallel digital outputs | 12-bit LVCMOS outputs per channel; output voltage swing referenced to OVDD (0.5–3.6 V); MSB-aligned. |
| CLKOUT | Data-ready strobe | Falling-edge-aligned clock derived from CLKB; used to latch parallel output data with <0.6 ns skew tolerance. |
| SHDNA, SHDNB | Per-channel shutdown control | Configures nap/sleep modes; reduces power to 15 mW or 2 mW per channel when inactive. |
| MODE | Output format & duty cycle stabilizer | Selects offset binary/2's complement and enables/disables clock duty cycle stabilizer for robust timing margin. |
| SENSEA, SENSEB | Input range programming | Set ±0.5 V (tie to VCMA/VCMB), ±1 V (tie to VDD), or custom range (external 0.5–1 V reference). |
| OF | Overflow/underflow flag | Open-drain active-high output shared by both channels; indicates clipping on either A or B path. |
| VDD, GND, OGND, OVDD | Supply and ground rails | VDD (2.85–3.4 V) powers analog core; OVDD (0.5–3.6 V) sets digital output swing; exposed pad must be soldered to PCB ground. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

| LTC2285CUP#TRPBF | 14-bit, 125 Msps, pin-compatible dual ADC; higher 73.5 dB SNR but 915 mW power vs. 790 mW. | Better dynamic range for precision measurement; higher power and cost limit portable/battery use. | Choose when SNR >72 dB is mandatory and thermal budget allows +125 mW per device. |
Compared with AD9233BCPZ-125, the LTC2283CUP#TRPBF eliminates external synchronization circuitry and reduces component count for dual-path systems; compared with LTC2285CUP#TRPBF, it trades 2.3 dB SNR for 16% lower power and lower cost-ideal for size- and power-constrained communications receivers.

FAQ
What is the operating temperature range for the LTC2283CUP#TRPBF?
The LTC2283CUP#TRPBF is specified for commercial-grade operation from 0°C to 70°C ambient temperature. This grade is validated per the Absolute Maximum Ratings table and supported by full characterization of DC accuracy, dynamic performance, and timing parameters across that range. The 'C' suffix in the part number explicitly denotes this temperature grade, distinguishing it from the industrial-grade LTC2283IUP#TRPBF (–40°C to 85°C).
Does the LTC2283CUP#TRPBF support single-ended analog input?
Yes, the LTC2283CUP#TRPBF supports single-ended analog input: connect the signal to AIN+ and tie AIN– to 1.5 V (VCMA or VCMB). However, this configuration degrades harmonic distortion and INL while preserving SNR and DNL. For optimal performance-especially SFDR above 80 dB-differential drive with matched 100 Ω source impedance is strongly recommended per the Applications Information section.
How does the MODE pin affect the LTC2283CUP#TRPBF functionality?
The MODE pin on the LTC2283CUP#TRPBF controls two functions simultaneously: output data format (offset binary or 2's complement) and clock duty cycle stabilizer enable/disable. Ground selects offset binary with stabilizer off; 1/3 VDD selects offset binary with stabilizer on; 2/3 VDD selects 2's complement with stabilizer on; VDD selects 2's complement with stabilizer off. This dual control applies identically to both ADC channels.
Can the LTC2283CUP#TRPBF drive 1.8 V logic levels directly?
Yes, the LTC2283CUP#TRPBF can drive 1.8 V logic directly using its dedicated OVDD supply rail. When OVDD = 1.8 V, the digital outputs (DA0–DA11, DB0–DB11, CLKOUT, OF) meet VOH ≥ 1.79 V and VOL ≤ 0.09 V under load, satisfying standard 1.8 V LVCMOS input thresholds. No external level shifters are required-simply route OVDD to the target FPGA or ASIC's 1.8 V I/O bank.
What is the purpose of the OF (overflow/underflow) pin on the LTC2283CUP#TRPBF?
The OF pin on the LTC2283CUP#TRPBF is an open-drain, active-high flag indicating overflow or underflow on either Channel A or Channel B. It asserts when input voltage exceeds the selected full-scale range (e.g., >±1 V for 2 Vpp mode), signaling potential clipping. This shared status output simplifies monitoring in dual-channel systems and can trigger automatic gain control or alert logic without polling individual channel data words.
