軟件可編程增益放大器

AD526是一款單端、單芯片軟件可編程增益放大器(SPGA)，提供1、2、4、8、16五種增益。它是一款完整的解決方案，配有放大器、電阻網(wǎng)絡(luò)和TTL兼容型鎖存輸入，無(wú)需外部器件。低增益誤差和低非線性度使AD526非常適合要求可編程增益的精密儀器應(yīng)用。增益為16時(shí)，小信號(hào)帶寬為350 kHz。此外，該器件具有出色的直流精度。FET輸入級(jí)使得偏置電流低至50 pA。利用ADI的激光調(diào)整技術(shù)，可保證最大輸入失調(diào)電壓為0.5 mV（C級(jí)），增益誤差低至0.01%（G = 1、2、4，C級(jí)）。AD526可以在鎖存模式或透明模式下工作，便于系統(tǒng)設(shè)計(jì)人員靈活使用。當(dāng)輸出與遠(yuǎn)端或低阻抗負(fù)載相連時(shí)，驅(qū)動(dòng) ? 數(shù)字可編程二進(jìn)制增益范圍：1至16\n? 雙芯片級(jí)聯(lián)模式可實(shí)現(xiàn) \n1至256的二進(jìn)制增益\n? 增益誤差:\n0.01%（最大值，增益 = 1、2、4，C級(jí)）\n0.02%（最大值，增益 = 8、16，C級(jí)）\n0.5 ppm/°C溫度漂移\n? 低非線性度：±0.005% FSR（最大值，J級(jí)）\n? 快速建立時(shí)間\n10 V 信號(hào)變化:\n4.5 μs（0.01%，增益 = 16）\n增益變化:\n5.6 μs（0.01%，增益 = 16）\n? 出色的直流精度:\n失調(diào)電壓：0.5 mV（最大值，C級(jí)）\n失調(diào)電壓漂移：3 μV/°C（C級(jí)）;
