Description : CMOS, 10-Bit, A/D Converters with Internal Track and Hold

The Intersil CA3310 is a fast, low power, 10-Bit successive approximation Analog-to-digital converter, with microprocessor-compatible outputs. It uses only a single 3V to 6V supply and typically draws just 3mA when operating at 5V. It can accept full rail-to-rail input signals, and features a built-in track and hold. The track and hold will follow high bandwidth input signals, as it has only a 100ns (typical) input time constant.

Description : LC2MOS High Speed, μP Compatible 8-Bit ADC with Track/Hold Function

GENERAL DESCRIPTION
The AD7821 is a high speed, 8-bit, sampling, Analog-to-digital converter that offers improved performance over the popular AD7820. It offers a conversion time of 660 ns (versus 1.36 µs for the AD7820) and 100 kHz signal bandwidth (versus 6.4 kHz). The sampling instant is better defined and occurs on the falling edge of WR or RD. The provision of a VSS pin (Pin 19) allows the part to operate from ±5 V supplies and to digitize bipolar input signals. Alternatively, for unipolar inputs, the VSS pin can be grounded and the AD7821 will operate from a single +5 V supply, like the AD7820.

FEATURES
  Fast Conversion Time: 660 ns Max
  100 kHz Track-and-Hold Function
  1 MHz Sample Rate
  Unipolar and Bipolar Input Ranges
  Ratiometric Reference Inputs
  No External Clock
  Extended Temperature Range Operation
  Skinny 20-Lead DlPs, SOIC, and 20-Terminal Surface-Mount Packages

Description : 8-Bit, high-speed, µP-compatible A/D converter with Track/Hold Function

DESCRIPTION
By using a half-flash conversion technique, the 8-bit ADC0820 CMOS A/D offers a 1.5µs conversion time while dissipating a maximum 75mW of power. The half-flash technique consists of 31 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC.
The input to the ADC0820 is tracked and held by the input sampling circuitry, eliminating the need for an external sample-and-hold for signals slewing at less than 100mV/µs.
For ease of interface to microprocessors, the ADC0820 has been designed to appear as a memory location or I/O port without the need for external interfacing logic.

FEATURES
• Built-in track-and-hold Function
• No missing codes
• No external clocking
• Single supply—5VDC
• Easy interface to all microprocessors, or operates stand-alone
• Latched 3-State outputs
• Logic inputs and outputs meet both MOS and TTL voltage level
   specifications
• Operates ratiometrically or with any reference value equal to or
   less than VDD
• 0V to 5V Analog input voltage range with single 5V supply
• No zero- or full-scale adjust required
• Overflow output available for cascading
• 0.3″ standard width 20-pin DIP

APPLICATIONS
• Microprocessor-based monitoring and control systems
• Transducer/µP interface
• Process control
• Logic analyzers
• Test and measurement
