Product details

250k SPS, 16-bit SAR ADC with four input channels

It accepts four analog inputs configurable as single-ended or pseudo-differential, with a 1:1 S/H-to-ADC ratio. The parallel data interface and external reference give the system designer direct control over conversion timing and voltage span.

Input flexibility and supply rails

Four analog inputs can be used as four single-ended channels or paired into two pseudo-differential pairs. The pseudo-differential mode rejects common-mode noise on the return path, which helps when the signal source is remote from the ADC. Both analog and digital sections run from ±5 V supplies, so the digital I/O levels are 5 V logic — not 3.3 V. If your system uses a 3.3 V host, level translation on the parallel bus is required.

Housed in a 48-pin TQFP measuring 7x7 mm, the ADS8342IBPFBT is a surface-mount device. The supplier device package is 48-TQFP (7x7).

It is ROHS3 compliant.

Frequently asked questions

How many inputs does ADS8342IBPFBT have and can it be used for single-ended signals?

It has four analog inputs that can be configured as four single-ended channels or as two pseudo-differential pairs. The input type is listed as both pseudo-differential and single-ended, so yes, single-ended operation is supported.

Can ADS8342IBPFBT work with a 3.3V supply?

No. Both the analog and digital supply voltages are specified as ±5 V. The digital interface operates at 5 V logic levels, so a 3.3 V host would require level translation on the parallel bus.

What is the equivalent or replacement for ADS8342IBPFBT?

The ADS1285IRHBT is a different architecture (32-bit sigma-delta, 4k SPS, SPI interface) and is not a pin-compatible or functional replacement. For a like-for-like replacement, stay within the ADS8342 family.
