Product details
Overview
LTC2236IUH#TRPBF from Analog Devices (acquired Linear Technology) is a 10-bit, 25Msps low-noise 3V analog-to-digital converter optimized for high-dynamic-range signal digitization in demanding communications and imaging systems. It delivers 61.8dB SNR, 85dB SFDR at Nyquist, ±0.1LSB typical INL, operates from a single 2.7V–3.4V supply, and consumes only 75mW - enabling portable and power-sensitive instrumentation.
For engineers reviewing the LTC2236IUH#TRPBF datasheet, LTC2236IUH#TRPBF pinout, LTC2236IUH#TRPBF application, or LTC2236IUH#TRPBF equivalent, key selection considerations include its 25Msps sampling rate, 575MHz full-power bandwidth, flexible 1VP-P to 2VP-P input range, clock duty cycle stabilizer, and shutdown/nap modes for system-level power management.
Technical Context
The LTC2236IUH#TRPBF implements a six-stage CMOS pipelined ADC architecture with integrated sample-and-hold, correction logic, and output drivers. Its differential input structure supports ±0.5V to ±1V ranges via SENSE pin configuration, and internal 1.5V VCM biasing enables direct transformer or op-amp driver interfacing.
It features a dedicated clock duty cycle stabilizer (enabled via MODE pin), 5-cycle pipeline latency, and configurable output format (offset binary or 2's complement). The device uses separate analog (VDD) and digital output (OVDD) supplies, allowing interface with 0.5V–3.6V logic families while maintaining analog performance integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit, no missing codes - guarantees monotonic transfer function for precision measurement applications. |
| Sampling Rate | 25Msps - fixed maximum conversion rate; determines real-time bandwidth limit (12.5MHz Nyquist). |
| SNR | 61.8dB at 5MHz input - defines minimum detectable signal level above quantization + thermal noise floor. |
| SFDR | 85dB at 5MHz input - indicates spurious-free dynamic range for multi-tone or modulated signal capture. |
| Power Dissipation | 75mW at 25Msps - enables thermally constrained PCB layouts and battery-powered operation. |
| Input Bandwidth | 575MHz full-power - supports wideband RF/IF sampling without external anti-alias filtering up to ~500MHz. |
| INL / DNL | ±0.5LSB max INL, ±0.5LSB max DNL - ensures accurate amplitude linearity across full temperature range (–40°C to +85°C). |
Pinout & Package
Package: 32-pin (5mm × 5mm) QFN with exposed thermal pad (Pin 33 = GND). Requires soldering of exposed pad to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN+, AIN– | Differential analog input | Accepts ±0.5V to ±1V differential signal; common-mode voltage centered at 1.5V (VCM pin). |
| REFH, REFL | ADC reference terminals | Shorted pairs; require local 0.1µF + 2.2µF bypassing to stabilize reference voltage for accuracy. |
| CLK | Sample clock input | Single-ended; sampling triggered on rising edge; duty cycle stabilizer reduces sensitivity to clock asymmetry. |
| SHDN, OE | Power mode control | SHDN=VDD + OE=GND → nap mode (15mW); SHDN=VDD + OE=VDD → shutdown (2mW). |
| D0–D9 | Parallel digital outputs | 10-bit offset binary or 2's complement data; MSB = D9; output drive compatible with 0.5V–3.6V logic (OVDD-supplied). |
| MODE, SENSE | Configuration inputs | MODE sets output format & duty cycle stabilizer; SENSE selects input range (±0.5V to ±1V) and reference source. |
| OF | Over/underflow flag | Active-high indicator of input signal exceeding selected full-scale range - critical for AGC loop feedback. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise 3V operation | 61.8dB SNR at 25Msps enables high-fidelity digitization of weak RF/ultrasound signals without gain-stage noise amplification. |
| Flexible input range | 1VP-P to 2VP-P programmable via SENSE pin - simplifies front-end design across varying sensor or IF signal levels. |
| Integrated clock duty cycle stabilizer | Allows robust operation with non-50% clock duty cycles - eliminates need for external clock conditioning circuitry. |
| Multiple low-power modes | 75mW active, 15mW nap, 2mW shutdown - supports dynamic power scaling in portable or burst-mode systems. |
| On-chip 1.5V VCM reference | Provides precise, low-drift common-mode bias for differential drivers - reduces component count and layout sensitivity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS5270IPFP | 10-bit, 40Msps, 1.8V core supply, LVDS outputs - higher speed but requires dual supply and serializer interface. | Targets higher-bandwidth medical imaging systems where 40Msps and serial output reduce routing complexity. | Select when system demands >25Msps or needs embedded JESD204B-like serialization; not drop-in due to supply and interface mismatch. |
| MAX1186ETI+ | 10-bit, 20Msps, 3V supply, 70mW, SPI-configurable - lower speed, integrated reference, no duty cycle stabilizer. | Suitable for cost-sensitive portable diagnostics where configurability and smaller footprint outweigh SNR/SFDR margin. | Choose for simplified BOM and SPI-based calibration; avoid if 25Msps or 85dB SFDR at high input frequencies is required. |
Compared with ADS5270IPFP and MAX1186ETI+, the LTC2236IUH#TRPBF provides optimal balance of 25Msps throughput, 61.8dB SNR, and ultra-low 75mW power in a simple parallel-output QFN package - ideal for space- and power-constrained instrumentation where analog performance must be preserved without complex interface overhead.

FAQ
What is the maximum sampling rate supported by the LTC2236IUH#TRPBF?
The LTC2236IUH#TRPBF is rated for a maximum sampling rate of 25Msps. This is a fixed specification - it cannot operate at the higher rates of the LTC2237 (40Msps) or LTC2238 (65Msps) in the same family. Operation beyond 25Msps may cause timing violations, increased jitter, or data corruption.
Does the LTC2236IUH#TRPBF support differential or single-ended analog inputs?
The LTC2236IUH#TRPBF supports both configurations. Differential input (AIN+ and AIN–) is recommended for optimal AC performance, delivering full 61.8dB SNR and 85dB SFDR. Single-ended operation (AIN+ driven, AIN– tied to VCM) is supported but degrades harmonic distortion and INL - DNL and SNR remain unaffected.
How does the MODE pin affect the operation of the LTC2236IUH#TRPBF?
The MODE pin configures two functions: output data format (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. Stabilizer improves timing margin with asymmetric clocks.
What power supply requirements does the LTC2236IUH#TRPBF have?
The LTC2236IUH#TRPBF requires two supplies: VDD (2.7V–3.4V, analog core, 25mA typical) and OVDD (0.5V–3.6V, digital outputs, current depends on load). GND and OGND must be connected together. Exposed thermal pad (Pin 33) must be soldered to PCB ground for thermal dissipation and noise reduction.
Is the LTC2236IUH#TRPBF pin-compatible with other devices in the LTC223x family?
Yes - the LTC2236IUH#TRPBF shares identical 32-pin QFN (UH) packaging, pinout, and footprint with LTC2237IUH#TRPBF and LTC2238IUH#TRPBF. This allows hardware reuse across 25/40/65Msps variants, though firmware and timing constraints must be updated to match the selected device's maximum sample rate.
