  • TMP421-Q1: Does A0 and A1 address pins in FLOAT mode means that V+/2 will be used

    Part Number: TMP421-Q1 Hi Team, Our customer use the TMP421-Q1 parts in a very noisy application, where floating pins are not allowed. Is it possible to use an external resistor divider to manage the FLOAT adressing mode? They use the FLOAT (1.65V) level…

  • TMP421-Q1: Remote temperature error

    TI Thinks Resolved
    Part Number: TMP421-Q1 Other Parts Discussed in Thread: DXP I am reading xC0 00 from the external 2N3906 transistor. Connected as shown on page 1 of the data sheet with the emitter grounded at the remote location. The internal reading seems to be correct…

  • TMP421-Q1: I2C Bus Design

    TI Thinks Resolved
    Part Number: TMP421-Q1 Other Parts Discussed in Thread: TMP421 Hi, The TMP421 description is I2C/SMBus Temperature Sensor. My question is, can the TMP421 work on the same I2C bus as an AT24CM02 EEPROM? As far as i can tell the EEPROM's address (0xA4…

  • TMP422-Q1: how to select slave address with two TMP422-Q1?

    TI Thinks Resolved
    Part Number: TMP422-Q1 Other Parts Discussed in Thread: TMP422 , DXP , , TMP421-Q1 Hi Team, My customer is planning use two TMP422 but just use one transistor, from datasheet page 17, the unuse channel DXP must be connect to GND and DXN must be left…

  • RE: TMP422: Temperature Monitoring Diode change from LM95233 to TMP422 possible?

    The schematic shown for LM95233 and ADC12QJ1600 features the ADC connected as remote temperature channel 1. The NPN, Q1, is connected as channel 2. The Q1 device is not necessary to measure the temperature of the ADC. In fact, a 2nd ADC could be connected…

  • RE: TMP421: TMP421A P2P Products

    If both of your TMP421's address pins were grounded, you could drop-in a TMP422 or TMP442. If your remote junction's return (DXN) is grounded and TMP421's A0 is grounded, you could use a TMP423. You could use the automotive grade (Q1) of any of these…
