Does TI have suitable solution to replace ADUC831BSZ?

Hi Jimmy,

Let's see if I can help narrow down a replacement. 

What operating voltage?

The ADUC831BSZ has a 16-bit sigma-delta ADC.  Is this a requirement the replacement should have?

Is there a specific package type and # of pins?

Hi Dennis,

Basically, based on ADUC831 spec to replace.

As I check, ADUC831BSZ has a 12-bit sigma-delta ADC.  

Hi Jimmy,

You are correct. My bad. Had too many different datasheets open at the same time.

Ok, so assuming a direct replacement with the following major features to match:

-16MHz
- 62kB FLASH/EE (PGM)
- 4kB on-chip FLASH/EE (DATA)
- 2kB RAM
- (2) 12-bit DAC
- 8 ch, 12-bit ADC (247kSPS or higher)
- On chip VREF
- (3) timers
- (2) 16-bit PWM
- WDT
- UART
- I2C
- SPI
- PSM
- +3 to +5v operation
- low power current 20uA @3v
- package is 52 or 56 pin

No matches for the following requirements

1. Required VDD operation is > 3.6v
2. (2) 12-bit DAC

Because of these two requirements, no matches are available.  Do you require VDD > 3.6 and (2) 12-bit DACs?

Hi team,

yes, custoemr need DAC. otherwise, they will not pick up this.
