Micronetics has now come to market with a 128-to-160-MHz, ultra-low-noise voltage-controlled oscillator (VCO). Known as the MW500-1343, this VCO has an exceptionally low phase-noise level of −147 dBc/Hz at around 100 kHz. The phase-noise level is −125 dBc/Hz at around 10 kHz and −100 dBc/Hz at around 1 kHz. Its power output is +10.5 dBm + 1.5 dB with a +12-V supply (31 mA). The VCO's stability is further assured by pushing and pulling of only 0.06 MHz/V and 0.13 MHz p-p, respectively. Its harmonics are at least 20 dB down. The tuning voltage range for 128 to 160 MHz is 0 to 13 V. But the VCO can operate up to 20-V tuning, which provides 178 MHz at reduced power (+6 dBm). It comes in a 0.500-in.2-x-0.15-in. surface-mounted package. Its modulation bandwidth is 123 MHz (−3 dB), which is exceptionally fast for this low operating frequency. The temperature drift is only −0.02 MHz/°C. For more information on the Micronetics VCO, go to www.micronetics.com.

Maxim Integrated Products recently introduced the MAX1963/MAX1976 regulators. The company claims that they are the world's first and smallest 100-mV low-dropout (LDO) linear regulators to operate from a 1.62-V input and deliver a guaranteed 300-mA continuous-load current. Typically, these linear regulators are used to power processor curves at 1.5 V. The devices have only 17% (typical) efficiency loss when powered from a 1.8-V I/O supply versus 61% using other linear regulators that are powered from a 3.8-V lithium-ion battery.
The MAX1963/MAX1976 provide very high output-voltage accuracy (±1.5%) over all load, line, and temperature conditions. These ICs are available in fixed-output voltages ranging from 0.75 to 3.0 V. Their active-low, open-drain reset output remains asserted for at least 2.2 ms (MAX1963) or 70 ms (MAX1976) after the output voltage reaches regulation.
The MAX1963 and MAX1976 have an internal PMOS pass transistor. Thus, the low 70-microamp supply current remains independent of load and dropout voltage. Other features include a logic-controlled shutdown, short-circuit protection, and thermal-overload protection.
The MAX1963/MAX1976 are available in 6-pin SOT23 and 6-pin, 3-x-3-mm TDFN packages. They are screened for the extended industrial temperature range (−40 to +85°C). Prices start at $0.62 (2500-up, FOB USA). For more details, go to www.maxim-ic.com.

National Semiconductor Corp. now offers a Boomer audio subsystem for cell phones. It integrates amplifiers, volume, and mixing controls along with 3D sound in a miniature micro-SMD package. The LM4857 integrates stereo speaker drivers for the handset with 495-mW output power per channel, a 33-mW stereo-headphone driver with 32-step volume control, and independent left, right, and mono volume controls. Operating on a 3.3-V supply, it combines a stereo-speaker amplifier for improved sound quality over single mono speakers; a mono earpiece amplifier that delivers 43 mW into a 32-W load; and a line output for an externally powered hands-free speaker (such as a car kit).
The LM4857's 3D enhancement improves stereo channel separation when the left and right speakers are too close together. It also solves problems that would otherwise arise from system size constraints or equipment limitations.
In addition, the LM4857 routes and mixes the stereo and mono inputs into 16 distinct output modes. Those modes give designers flexibility to route and mix audio signals without limiting routing just to stereo speakers or headphones. The LM4857 is controlled through an I2C-compatible interface. Now available in a 30-bump micro-SMD package, it is priced at $2.70 in 1000-unit quantities. To get more information on the LM4857, go to the company web site at www.national.com.

Linear Technology Corp. has introduced the LTC2600 family of low-cost, low-power voltage-output DACs. The outputs feature monotonic performance and the capability of driving up to 1000 pF. Such high integration is achieved with remarkably low crosstalk. Adjusting one DAC will not affect the others. Operating from supplies as low as 2.5 V, this family perfectly suits tiny, cost-sensitive closed-loop or trim/adjust applications.
The LTC2602/LTC2612/LTC2622 are dual 16-, 14-, and 12-b, 2.5-to-5.5-V, rail-to-rail voltage-output DACs in a tiny 8-lead MSOP package. They have built-in high-performance output buffers and are guaranteed monotonic. These parts offer advanced performance for output drive, crosstalk, and load regulation in single-supply, voltage-output multiples. They use a simple SPI/MICROWIRE-compatible, 3-wire serial interface that can be operated at clock rates up to 50 MHz.
The LTC2602/LTC2612/LTC2622 incorporate a power-on-reset circuit. During power up, the voltage outputs rise less than 10 mV above zero scale. After power up, they stay at zero scale until a valid write and update take place. For more information, go to www.linear.com.
