CS4373

Low-power, High-performance ∆Σ Test DAC

Features

Description

The CS4373 is a differential output digital-to-

analog converter intended for high-resolution,

low-frequency measurement systems. It is de-

signed to work with the CS5376A and CS5378

digital filters, the CS3301 and CS3302 high-pre-

cision amplifiers, and the CS5371 or CS5372

high-performance ∆Σ modulators.

• Digital ∆Σ Input, Differential Analog Output

• Selectable Differential Outputs (^{OUT , BUF})

• Selectable Output Attenuation

- 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64

• User-programmable Test Modes

- Differential

- Common mode

The CS4373 includes a set of multiplexed out-

puts which provide a precision output (OUT±) for

testing the electronics channel and a buffered

output (BUF±) for in-circuit sensor tests. It is driv-

en by a ∆Σ bitstream and the maximum analog

output is differential 5 volts peak-to-peak. Distor-

tion performance of the DAC is typically -118 dB

THD from the precision output, and -100 dB THD

from the buffered output. Noise performance is

114 dB SNR over a 430 Hz bandwidth.

• Output Voltage: 5 V

Differential

P-P

• Outstanding Noise Performance

- 114 dB SNR @ 430 Hz bandwidth

• Low Total Harmonic Distortion

- OUT±: -118 dB THD typical, -112 dB THD max

- BUF±: -100 dB THD typical, -95 dB THD max

• Low Power Consumption

- Normal mode: 7.8 mA

- Low power mode: 5.0 mA

- Power down: 400 µA

- Sleep mode: 2 µA

The CS4373 has very low power consumption. In

normal mode (LPWR=0; MCLK=2.048 MHz),

power consumption is 40 mW; while in Low Pow-

er mode (LPWR=1; MCLK=1.024 MHz), power

consumption is 25 mW.

• Power Supply Options

- VA+ = +5 V;

VA- = 0 V;

VD = +3.3 V to +5 V

- VA+ = +2.5 V; VA- = -2.5 V; VD = +3.3 V
