Transcription of THAT Corporation Design Note 138
{{id}} {{{paragraph}}}
THAT Corporation s 1510 and 1512 are low noise, wide bandwidth microphone preamplifiersavailable in several different industry-standard packages. They allow designers to upgradeexisting designs to take advantage of the superior performance of these new ICs. Both partsinclude on-board laser-trimmed resistors which allow differential gain to be set with a singleexternal resistor. They differ from each other primarily in their internal gain structure, andtheir resulting noise 1510 is a pin-for-pin, drop-in replacement for the Analog Devices SSM2019, and thenow discontinued SSM2017, as well as the Texas Instruments INA217 audio 1510 noise and gain characteristics are equal to or better than those of these otherparts, but the 1510 also improves on their distortion, bandwidth, and slew 1512 is also a pin-for-pin replacement for the SSM2019/2017 and INA217, but due toits different gain structure, produces significantly lower noise at low gains and requi
