MPY634 is a wide bandwidth, high accuracy, four-quadrant analog multiplier with features of high precision, low cost and easy to use.

REG710 is a switched capacitor voltage converter from Schneider Electric that produces a regulated, low-ripple output voltage from an unregulated input voltage. The input voltage range is wide, from 1.8V to 5.5V, making it ideal for a variety of battery sources, such as single cell Li-Ion batteries, or two and three cell nickel- or alkaline-based chemistries. The input voltage may vary above and below the output voltage and the output will remain in regulation. It works equally well for step-up or step-down applications without the need for an inductor, providing low EMI DC/DC conversion. The high switching frequency allows for the use of small capacitors, reducing input current ripple.

ADS8320 is a 16-bit, high-speed, low-power analog-to-digital converter (ADC) from Analog Devices. It features a sampling rate of 100 kHz and a power consumption of just 3µA. The device is available in an MSOP-8 package.

The BUF01900/1901 is a programmable voltage output product with 10-bit resolution. Programming of the output occurs through an industry-standard, two-wire serial interface. Once the correct VCOM voltage is established it can easily be stored into the integrated nonvolatile memory. An initial output voltage and adjustment range can be set by an external resistor-divider. With its large output current capability (up to 100mA), the BUF01900 and BUF01901 are ideally suited as programmable VCOM calibrators in LCD panels. The BUF01901 has the digital-to-analog converter (DAC) output brought out directly. It has a slightly lower cost than the BUF01900, and works very well with the integrated VCOM in traditional LCD panels.

The PCM3500 is a 16-bit low voltage, low power, mono VOICE/MODEM CODEC, which is suitable for software modems, portable voice recorders, speech recognition/synthesis, etc.

The PCM3793A is a 16-bit, low-power, stereo audio codec with microphone bias, headphone, and digital speaker amplifier.

INA116 is an ultra low input bias current instrumentation amplifier produced by Burr-Brown Corporation. It has extremely low input bias current and high common-mode rejection ratio.

The OPA227 and OPA228 series op amps combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both ac and precision dc performance. The OPA227 is unity-gain stable and features high slew rate (2.3V/µs) and wide bandwidth (8MHz). The OPA228 is optimized for closed-loop gains of 5 or greater, and offers higher speed with a slew rate of 10V/µs and a bandwidth of 33MHz. The OPA227 and OPA228 series op amps are ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applications requiring high precision. The OPA227 and OPA228 series op amps are pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board. The dual channel OPA4227 and OPA2227 are fully compatible replacements for the single channel OPA227 and OPA228.

The DAC7621 is a 12-bit digital-to-analog converter (DAC) with guaranteed 12-bit monotonicity performance over the industrial temperature range. It requires a single +5V supply and contains an input register, latch, 2.435V reference, DAC, and high speed rail-to-rail output amplifier. For a full-scale step, the output will settle to 1 LSB within 7µs. The device consumes 2.5mW (0.5mA at 5V). The parallel interface is compatible with a wide variety of microcontrollers. The DAC7621 accepts a 12-bit parallel word, has a double-buffered input logic structure and provides data readback. In addition, two control pins provide a chip select (CS) function and asynchronous clear (CLR) input. The CLR input can be used to ensure that the DAC7621 output is 0V on power-up or as required by the application. The DAC7621 is available in a 20-lead SSOP package and is fully specified over the industrial temperature range of –40°C to +85°C.

The INA163 is a very low-noise, low-distortion, monolithic instrumentation amplifier. Its current-feedback circuitry achieves very wide bandwidth and excellent dynamic response over a wide range of gain. It is ideal for low-level audio signals such as balanced low- impedance microphones. Many industrial, instrumen- tation, and medical applications also benefit from its low noise and wide bandwidth. Unique distortion cancellation circuitry reduces distor- tion to extremely low levels, even in high gain. The INA163 provides near-theoretical noise performance for 200Ω source impedance. Its differential input, low noise, and low distortion provide superior performance in professional microphone amplifier applications. The INA163’s wide supply voltage, excellent output voltage swing, and high output current drive allow its use in high-level audio stages as well. The INA163 is available in a space-saving SO-14 surface-mount package, specified for operation over the –40°C to +85°C temperature range.
