Product details
Overview
LTC2227CUH#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 40Msps low-power 3V analog-to-digital converter optimized for high-dynamic-range signal digitization in demanding communications and imaging systems. It delivers 71.4dB SNR and 90dB SFDR at Nyquist, features ±0.3LSB typical INL, 575MHz full-power bandwidth, and operates from a single 3V supply with flexible 0.5V–3.6V output logic interface.
For engineers reviewing the LTC2227CUH#TRPBF datasheet, LTC2227CUH#TRPBF pinout, LTC2227CUH#TRPBF application, or LTC2227CUH#TRPBF equivalent, key selection criteria include its 40Msps sampling rate, differential input support, clock duty cycle stabilizer, shutdown/nap modes, and QFN-32 package compatibility with the LTC2228/LTC2226 family.
Technical Context
The LTC2227CUH#TRPBF implements a six-stage CMOS pipelined ADC architecture with digital correction logic, achieving 5-cycle pipeline latency and aperture jitter of 0.2psRMS. Its sample-and-hold circuit supports both differential and single-ended analog inputs, with common-mode voltage programmable via VCM (1.5V ±25ppm/°C) and input range selectable from ±0.5V to ±1V using the SENSE pin.
It integrates a clock duty cycle stabilizer (enabled via MODE pin biasing), flexible reference configuration (internal or external), and independent OVDD supply for output driver level-shifting. DC performance includes no missing codes over temperature, ±0.15LSB typical DNL, and transition noise of 0.25LSBRMS.

FAQ
What is the operating temperature range for the LTC2227CUH#TRPBF?
The LTC2227CUH#TRPBF is specified for commercial-grade operation from 0°C to 70°C ambient temperature. This range is confirmed in the Order Information table and Absolute Maximum Ratings section of the datasheet, and applies to all DC and AC performance specifications unless otherwise noted.
Does the LTC2227CUH#TRPBF support differential or single-ended analog inputs?
The LTC2227CUH#TRPBF supports both configurations: differential input (recommended for optimal AC performance) using AIN+ and AIN– pins, and single-ended input (for cost-sensitive designs) using AIN+ referenced to AIN– tied to VCM. The datasheet confirms differential drive yields better SFDR and harmonic suppression.
How does the MODE pin affect the LTC2227CUH#TRPBF's output format and clock function?
The MODE pin on the LTC2227CUH#TRPBF selects both output coding (offset binary or 2's complement) and clock duty cycle stabilizer enable/disable. Ground = offset binary + stabilizer off; 1/3 VDD = offset binary + stabilizer on; 2/3 VDD = 2's complement + stabilizer on; VDD = 2's complement + stabilizer off - all explicitly defined in the PIN FUNCTIONS section.
What is the purpose of the OF (Over/Under Flow) pin on the LTC2227CUH#TRPBF?
The OF pin on the LTC2227CUH#TRPBF is an active-high flag indicating that the analog input exceeded the selected full-scale range (±0.5V or ±1V), causing saturation. It is asserted synchronously with the data output and remains high for one clock cycle after overflow occurs - verified in the PIN FUNCTIONS and TIMING DIAGRAM sections.
Can the LTC2227CUH#TRPBF operate with different output voltage levels?
Yes - the LTC2227CUH#TRPBF uses a dedicated OVDD supply (0.5V to 3.6V) for its parallel digital outputs (D0–D11), allowing direct interface to 1.8V, 2.5V, or 3.3V logic families without external level shifters. Output voltage thresholds scale with OVDD, as confirmed in the DIGITAL INPUTS AND DIGITAL OUTPUTS specification table.
