Product details
Overview
LTC2290CUP#TRPBF from Analog Devices (formerly Linear Technology) is a dual 12-bit, 10Msps low-power analog-to-digital converter operating from a single 3V supply (2.7V–3.4V), delivering 71.3dB SNR and 90dB SFDR at 5MHz input with 110dB channel isolation - used in high-fidelity spectral analysis and portable instrumentation signal chains.
For engineers reviewing the LTC2290CUP#TRPBF datasheet, LTC2290CUP#TRPBF pinout, LTC2290CUP#TRPBF application, or LTC2290CUP#TRPBF equivalent, key selection criteria include dual-channel synchronization, flexible 1VP-P to 2VP-P differential input range, clock duty cycle stabilization, multiplexed/parallel output bus support, and QFN-64 thermal performance for embedded imaging and communications front-ends.
Technical Context
The LTC2290CUP#TRPBF implements a six-stage CMOS pipelined ADC architecture per channel, with 5-cycle pipeline latency and separate sample-and-hold circuits for A/B channels. It supports both offset binary and 2's complement output formats via MODE pin configuration.
Each channel features independent reference programming (SENSEA/SENSEB), dedicated clock inputs (CLKA/CLKB), and configurable shutdown/nap modes. The integrated 1.5V VCM buffer and internal bandgap reference enable ±0.5V or ±1V differential input ranges without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes over temperature - guarantees monotonicity and full code coverage in closed-loop control or precision measurement. |
| Sample Rate | 10Msps maximum - enables real-time digitization of baseband signals up to 5MHz Nyquist bandwidth in spectrum analyzers. |
| SNR / SFDR | 71.3dB SNR and 90dB SFDR at 5MHz - supports >11-bit effective resolution for demanding RF IF sampling applications. |
| Power Consumption | 120mW typical at 10Msps - allows battery-powered portable instrumentation with dual-channel simultaneous sampling. |
| Input Bandwidth | 575MHz full-power bandwidth - accommodates wideband analog inputs without external anti-alias filtering below 100MHz. |
| Channel Isolation | 110dB crosstalk - prevents signal leakage between channels in dual-path receivers or time-interleaved architectures. |
| Supply Range | 2.7V–3.4V analog VDD; 0.5V–3.6V digital OVDD - supports mixed-voltage system interfacing to 1.8V/2.5V/3.3V logic families. |
Pinout & Package
64-pin (9mm × 9mm) plastic QFN package with exposed thermal pad (Pin 65 = GND). Requires soldering of exposed pad to PCB ground plane for thermal management (θJA = 20°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AINA+, AINA– AINB+, AINB– |
Differential analog inputs (Ch A & Ch B) | Accept ±0.5V or ±1V differential signals; require matched 100Ω source impedance for optimal SFDR. |

Per-channel shutdown & output enable | Enable nap mode (15mW/channel) or shutdown (2mW/channel); allow independent power gating per channel. |
| SENSEA, SENSEB | Reference range selection inputs | Set input range: tie to VCMA/VCMB for ±0.5V; to VDD for ±1V; or apply external voltage for custom ±VSENSE range. |
| MODE | Output format & clock stabilizer control | Selects offset binary/2's complement output and enables/disables internal clock duty cycle stabilizer. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent ADC cores | Enables true simultaneous sampling of two analog signals - critical for phase-coherent I/Q demodulation or stereo acquisition. |
| Integrated clock duty cycle stabilizer | Allows high AC performance even with 20%–80% input clock duty cycle - eliminates need for external clock conditioning circuitry. |
| Flexible digital output interface | Multiplexed or parallel 12-bit buses reduce PCB trace count and simplify FPGA/ASIC interface design in space-constrained systems. |
| Low transition noise (0.25LSBRMS) | Minimizes quantization uncertainty in high-resolution position sensing or vibration analysis where sub-LSB stability matters. |
| 110dB channel-to-channel isolation | Prevents inter-channel interference in dual-path receivers, enabling accurate amplitude/phase comparison without calibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel 12-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9233BCPZ-105 | 12-bit, 105Msps, single-channel only; requires external clock conditioner; higher power (340mW) | Higher speed but lacks native dual-channel synchronization; suited for single-path high-speed digitization only | Choose when sampling rate >10Msps is required and dual-channel correlation is not needed. |
| LTC2292IUP#TRPBF | 12-bit, 40Msps, same pinout and feature set; higher power (240mW); wider –40°C to 85°C temp grade | Drop-in speed upgrade with identical footprint and register map - no layout change required | Choose when system requires >10Msps while retaining same thermal and interface design. |
Compared with AD9233BCPZ-105 and LTC2292IUP#TRPBF, the LTC2290CUP#TRPBF uniquely balances ultra-low power (120mW), true dual-channel synchronization, and integrated clock stabilization - making it optimal for portable, phase-sensitive, and thermally constrained applications where 10Msps suffices.

FAQ
What is the operating temperature range for the LTC2290CUP#TRPBF?
The LTC2290CUP#TRPBF is specified for the commercial temperature range of 0°C to 70°C. This grade is validated for use in indoor instrumentation, lab equipment, and non-automotive portable devices where ambient conditions remain within this envelope. The 'C' suffix explicitly denotes this temperature grade, distinct from the industrial-grade 'I' variant (–40°C to 85°C). Thermal derating is not required within this range when PCB thermal pad is properly soldered.
Does the LTC2290CUP#TRPBF support single-ended analog inputs?
Yes, the LTC2290CUP#TRPBF supports single-ended analog inputs: drive AIN+ with the signal and connect AIN– to VCM (1.5V) or a quiet reference between 0.5V and 1.5V. However, harmonic distortion and INL degrade versus differential operation - SNR and DNL remain unchanged. For best performance, differential drive with matched 100Ω source impedance is strongly recommended.
How does the clock duty cycle stabilizer function in the LTC2290CUP#TRPBF?
The LTC2290CUP#TRPBF's internal clock duty cycle stabilizer, enabled via the MODE pin, corrects input clock asymmetry to maintain optimal aperture jitter performance. When active, it accepts CLK duty cycles from 20% to 80% and outputs a stabilized 50% ±5% internal clock - eliminating external duty cycle correction circuitry and preserving 71.3dB SNR at full 10Msps rate.
Can the LTC2290CUP#TRPBF operate with different analog and digital supply voltages?
Yes, the LTC2290CUP#TRPBF separates analog and digital supplies: VDD (2.7V–3.4V) powers the ADC core and references, while OVDD (0.5V–3.6V) independently powers the digital output drivers. This allows direct interfacing to 1.8V, 2.5V, or 3.3V logic families without level shifters - OGND must be tied to GND, and OVDD bypassing is required per datasheet layout guidelines.
What is the purpose of the SENSEA and SENSEB pins on the LTC2290CUP#TRPBF?
The SENSEA and SENSEB pins configure the full-scale input range per channel: tying to VCMA/VCMB selects ±0.5V (1VP-P), to VDD selects ±1V (2VP-P), or applying an external voltage between 0.5V and 1V sets ±VSENSE. This enables precise dynamic range matching to sensor output without external gain stages - each channel operates independently, supporting mixed-range signal acquisition in the same device.
