Medical Equipment

•

250-kHz Sampling Rate

Standard ±10-V Input Range

73-dB SINAD With 45-kHz Input

±0.45 LSB Max INL

Instrumentation

±0.45 LSB Max DNL

12 Bit No Missing Code

DESCRIPTION

±1 LSB Bipolar Zero Errors

±0.4 PPM/°C Bipolar Zero Error Drift

Single 5-V Supply Operation

The ADS8504 is a complete 12-bit sampling A/D

converter using state-of-the-art CMOS structures. It

contains a complete 12-bit, capacitor-based, SAR

A/D with S/H, reference, clock, interface for

microprocessor use, and 3-state output drivers.

Pin-Compatible With ADS7804/05 (Low Speed)

and 16-Bit ADS8505

The ADS8504 is specified at a 250-kHz sampling rate

over the full temperature range. Precision resistors

provide an industry standard ±10-V input range, while

the innovative design allows operation from a single

+5-V supply, with power dissipation under 100 mW.

Uses Internal or External Reference

Full Parallel Data Output

70-mW Typ Power Dissipation at 250 KSPS

28-Pin SOIC Package

The ADS8504 is available in a 28-pin SOIC package

and is fully specified for operation over the industrial

-40°C to 85°C temperature range.
