600ksps ADC with Shutdown

FEATURES

■

DESCRIPTIO

Complete 12-Bit ADC in SO-8

Single Supply 5V or

5V Operation

Sample Rate: 600ksps

Power Dissipation: 75mW (Typ)

72dB S/(N + D) and – 80dB THD at Nyquist

No Missing Codes over Temperature

Nap Mode with Instant Wake-Up: 7.5mW

Sleep Mode: 60µW

High Impedance Analog Input

Input Range (1mV/LSB): 0V to 4.096V or

2.048V

Internal Reference Can Be Overdriven Externally

3-Wire Interface to DSPs and Processors (SPI and

MICROWIRE

Compatible)

The LTC

1404 is a complete 600ksps, 12-bit A/D con-

verter which draws only 75mW from 5V or

5V supplies.

This easy-to-use device comes complete with a 160ns

sample-and-hold and a precision reference. Unipolar and

bipolar conversion modes add to the flexibility of the ADC.

The LTC1404 has two power saving modes: Nap and

Sleep. In Nap mode, it consumes only 7.5mW of power

and can wake up and convert immediately. In the Sleep

mode, it consumes 60µW of power typically. Upon power-

up from Sleep mode, a reference ready (REFRDY) signal

is available in the serial data word to indicate that the

reference has settled and the chip is ready to convert.

The LTC1404 converts 0V to 4.096V unipolar inputs from

a single 5V supply and

±2.048V

bipolar inputs from

±5V

supplies. Maximum DC specs include

±1LSB

INL,

±1LSB

DNL and 45ppm/°C full-scale drift over temperature.

Guaranteed AC performance includes 69dB S/(N + D)

and – 76dB THD at an input frequency of 100kHz over

temperature.

The 3-wire serial port allows compact and efficient data

transfer to a wide range of microprocessors, microcontrollers

and DSPs.
