Featuring a high-precision 25MHz crystal oscillator, dual output channels including a 5x amplified signal, and a wide operating temperature range (-40°C to +105°C), it is ideal for professional measurement, excitation, and sensing applications. Its software-programmable frequency and phase control, combined with Arduino compatibility, make it a powerful tool for engineers and developers seeking affordable, reliable signal generation. ## Description DollaTek trademark Reg.NO:013726393Description:Module Features:1.the working voltage: 2.3V-5.5V.2.the working temperature range: -40 ~ +105 ℃ .3.onboard 25MHZ (accuracy of 50ppm) active crystal, step accuracy of 0.1HZ.4.onboard 300M high-speed amplifier and a low-pass filter function.5. two output signal channels, an original signal output VOUT, an amplification of 5 times the signal output PGA, 50Ohm output impedance.6.very small size: 32mm X 32mm.Application:Frequency excitation / waveform generation.Liquid, air flow measurement.Sensing application - approach, motion, defect detection.Linear loss, linear attenuation.Test equipmentPack include:1x DollaTek AD9833 Triangular Sine Wave Signal Source IC Integrated Circuit Square Wave Generator Module Programmable Review: Excellent Sine Source - A very good little circuit. It is cheaper to buy this than a single AD9833 IC. I've tested it from 30mV to 3.5V sine wave. My requirement is 125kHz, but be aware that higher frequencies will start to loose gain because of the Gain Bandwidth Product. If you do need higher frequencies, you could likely swap out a pin compatible opamps with a higher GBWP. The AD9833 has an Arduino Library which is useful for quickly getting it going. For my application, this is a big step towards replacing an expensive signal generator. Review: Ok but not so good at the higher frequencies ## Features - The AD9833 is a programmable waveform generator capable of generating sine, triangular, and square wave signals with a frequency of 0-12.5MHZ. Waveform generators are widely used in a variety of measurement, excitation and time domain response areas - Output frequency and phase can be programmed by software, easy to adjust, clocked at 25MHz, the accuracy of 0.1Hz, clocked at 1MHz, the accuracy can reach 0.004Hz. Data can be written via 3 serial interfaces - Working voltage: 2.3V-5.5V. Operating temperature range: -40 ~ +105 ℃. - Onboard 25MHZ (precision 50ppm) active crystal, step accuracy of 0.1HZ. Onboard 300M high-speed amplifier and at the same time low-pass filter function. - Two output signal channels, an original signal output VOUT, an amplification of 5 times the signal output PGA, 50Ohm output impedance. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DJT8Z49 | | Best Sellers Rank | 25,657 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 20 in Function Generators | | Guaranteed software updates until | unknown | | Manufacturer | DollaTek | | Package Dimensions | 10 x 7 x 0.6 cm; 20 g | ## Images ![DollaTek AD9833 Triangular Sine Wave Signal Source IC Integrated Circuit Square Wave Generator Module Programmable - Image 1](https://m.media-amazon.com/images/I/61XTLwqkS4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Sine Source *by M***D on 2 August 2025* A very good little circuit. It is cheaper to buy this than a single AD9833 IC. I've tested it from 30mV to 3.5V sine wave.

In precedenza ho provato una scheda semplice solo con AD9833 ma probabilmente per causa del oscillatore a cristallo di qualità inferiore, ogni tanto la frequenza generata non era giusta. ## Frequently Bought Together - DollaTek AD9833 Triangular Sine Wave Signal Source IC Integrated Circuit Square Wave Generator Module Programmable - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - VooGenzek 120 PCS 2.54mm Breakaway PCB Board Pin Header Connector Strip Assortment Kit, Female Pin Header Socket Connector Strip, for Arduino Stackable Shield (4/6/8/10/12/16/20/40 Pin) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/121493384-dollatek-ad9833-triangular-sine-wave-signal-source-ic-integrated-circuit](https://www.desertcart.pl/products/121493384-dollatek-ad9833-triangular-sine-wave-signal-source-ic-integrated-circuit) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
