Quite a universal opamp. --- End quote --- TI are iterating on "universal opamp" with others like OPAx828, or chopper OPAx189 lots of progress with analog capabilities still growing. --- End quote --- Wow. Those are some impressive specs.. --- End quote --- THD + noise 0.00006% :scared: |

Meanwhile they provide PowerPAD packages for opamps to reduce self-heating. Amazing how improvements in analog technology still continue. |

I'm not sure if this is officially a chip of the day considering I haven't personally use it yet... but SQJQ184ER-T1_GE3 https://www.digikey.com/en/products/detail/vishay-siliconix/SQJQ184ER-T1-GE3/16181886 https://www.vishay.com/docs/71298/sqjq184er.pdf QTY UNIT PRICE EXT PRICE 1 $3.53000 $3.53 10 $2.96500 $29.65 100 $2.39890 $239.89 500 $2.13232 $1,066.16 1,000 $1.82579 $1,825.79 N-Channel MOSFET, 80V, 1.4mOhm Rds-on, 430A Id25, 600W 8-PowerSMD That is a serious little FET! |

This one could be super useful..... TPL5110QDDCRQ1 It's a timer/power gating high side switch chip. So for example if you want to only power up your system every x seconds, do something, then power down to save batteries. Timer intervals from 100ms to 7200s and 35nA quiescent current draw for this chip. Could be super useful if your system doesn't have a deep sleep mode or otherwise lots of quiescent current. https://www.digikey.com/en/products/detail/texas-instruments/TPL5110QDDCRQ1/6816812 https://www.ti.com/lit/ds/symlink/tpl5110-q1.pdf QTY UNIT PRICE EXT PRICE 1 $0.88000 $0.88 100 $0.61560 $61.56 1,000 $0.40148 $401.48 |
