MCP4725A1T-E/CH
Microchip TechnologyMCP4725A1T-E/CH is the A1-address order code for Microchip's 12-bit single-channel DAC with on-board EEPROM, I2C interface and buffered rail-to-rail output, in SOT-23-6 on tape and reel, 2.7 to 5.5 V supply, -40 to +125 °C. The EEPROM is the selection point: the DAC powers up to the stored output code without MCU initialization, which is what set-and-forget control outputs — bias trims, threshold references, drive levels — need to survive power cycles. Selection advice: the A1 in the code is a factory-programmed address option, not a grade — this variant answers at I2C addresses 0x62/0x63 (set by the A0 pin), where the A0T code on this site answers at 0x60/0x61, so the two codes can share one bus; A2T (0x64/0x65) and A3T (0x66/0x67) variants also exist in the DS20002039 ordering table. Confirm the address option against your bus map before ordering — an A1T will not respond at an A0T address. Performance facts: 6 µs settling, ±0.2 LSB DNL, I2C up to 3.4 MHz, per datasheet DS20002039.
