MAX262 Active Filter Module Programmable Filter High Low Pass Bandpass

<p><b style="font-size: 1em;">Features: </b><br></p><p>1. with a filter design software, with a microprocessor interface;</p><p>2. can control 64 different center frequency f0, 128 different quality factor Q and 4 kinds of work patterns;</p><p>3. the center frequency f0 and quality factor Q can be independently programmed;</p><p>4. can provide three clock input (external clock input, RC oscillator and crystal devices);</p><p>5. the central frequency f0 range of 1Hz ~ 140kHz, the maximum input clock 4MHz;</p><p>6. the filter circuit structure is simple, less external components, small size;</p><p>7. can achieve low-pass, high-pass, band-pass, band-stop and all-pass filter;</p><p>8. can be A, B single-stage input and output, but also AB cascade of two levels of input and output;</p><p>9. Product size: 50*50MM</p><p>10. Product weight: 22 grams</p><p><br></p><p><b>The main chip pin description:</b></p><p>V +  - positive power input.</p><p>V-  -Negative power input.</p><p>GND - Analog ground.</p><p>CLKA - external crystal oscillator and filter A part of the clock input, within the filter, the clock frequency is divided by 2.</p><p>CLKB - the clock input to filter B, also within the filter, the clock frequency is divided by 2.</p><p>CLKOUT - Clock output for crystal oscillator and R-C oscillation.</p><p>OSCOUT - Connects to a crystal or R-C oscillator for self-synchronization.</p><p>INA, INB - The signal input of the filter.</p><p>BPA, BPB - band-pass filter output.</p><p>LPA, LPB - low-pass filter output.</p><p>HPA, HPB - high-pass, with resistance, all-pass filter output.</p><p>WR - Writing to the active input. When connected to V +, the data can be entered into a programmable memory through the logical interface to complete the filter mode, f0 and Q settings. In addition, it can receive TTL level signals, and the rising edge latch input data.</p><p>A0, A1, A2, A3 - address input, can be used to complete the filter mode, f0 and Q of the corresponding settings.</p><p>D0, D1 - Data input, can be used to set the corresponding bits f0 and Q.</p><p>OP OUT - The amplifier output of the MAX262.</p><p>OP IN - The inverting input of the MAX262 amplifier.</p><p><br></p><p><b>Packing list:</b></p><p>Program-controlled filter * 1</p><p><br></p><p><img src="https://cf.cjdropshipping.com/cc869304-eec9-48be-b38d-66307560b74a.jpg" style="max-width:100%;"><img src="https://cf.cjdropshipping.com/6d614f3f-4f1d-4f42-8f97-c120873a8314.jpg" style="max-width: 100%;"><img src="https://cf.cjdropshipping.com/7a4fad0c-caad-422d-93d4-05971b6e99ea.jpg" style="max-width: 100%;"><img src="https://cf.cjdropshipping.com/bf577c8d-c0ad-4c09-8bc0-971692704763.jpg" style="max-width: 100%;"><img src="https://cf.cjdropshipping.com/96f669a6-cf64-4fa1-aa93-29c957c00c35.jpg" style="max-width: 100%;"><br></p>
