Microchip Technology TC7109
The TC7109A is a 12-bit plus sign, CMOS low power Analog-to-Digital Converter (ADC). The improved VOH source current and other TC7109A features make it an attractive per-channel alternative to analog multiplexing for many data acquisition applications. These features include typical input bias current of 1pA, drift of less than 1 V/°C, input noise typically 15 VP-P, and auto-zero.| Part No. | TC7109 |
