description

The THS7001 (single) and THS7002 (dual) are high-speed programmable-gain amplifiers, ideal for applications where load impedance can often vary. Each channel on this device consists of a separate low-noise input preamp and a programmable gain amplifier (PGA). The preamp is a voltage-feedback amplifier offering a low 1.7-nV/ Hz voltage noise with a 100-MHz (±3 dB) bandwidth. The output pin of the preamp is accessible so that filters can be easily added to the amplifier.

The 3-bit digitally-controlled PGA provides a ±22-dB to 20-dB attenuation/gain range with a 6-dB step resolution. In addition, the PGA provides both high and low output clamp protection to prevent the output signal from swinging outside the common-mode input range of an analog-to-digital converter. The PGA provides a wide 70-MHz (±3 dB) bandwidth, which remains relatively constant over the entire gain/attenuation range. Independent shutdown control is also provided for power conservation and multiplexing. These devices operate over a wide ±4.5-V to ±16-V supply voltage range.

input preamp

To achieve the minimum input equivalent noise required for very small input signals, the input preamp is configured as a classic voltage feedback amplifier with a minimum gain of 2 or ±1. The output of the preamp is accessible, allowing for adjustment of gain using external resistors and for external filtering between the preamp and the PGA.

programmable gain amplifier (PGA)

The PGA is an inverting, programmable gain amplifier. The gain is digitally programmable using three control bits (TTL-compatible terminals) that are encoded to provide eight distinct levels of gain/attenuation. Nominal gain/attenuation is shown in Table 1.

Output clamping for both upper (VH) and lower (VL) levels for the PGAs is provided. There is only one terminal for the positive output clamp and one for the negative output clamp for both channels.

shutdown control

The SHDN terminals allow for powering down the internal circuitry for power conservation or for multiplexing. Separate shutdown controls are available for each channel. The control levels are TTL compatible.

²Stresses beyond those listed under ªabsolute maximum ratingsº may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under ªrecommended operating conditionsº is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. The THS7001 and THS7002 incorporates a PowerPAD on the underside of the chip. The PowerPAD acts as a heatsink and must be connected to a thermal dissipation plane for proper power dissipation. Failure to do so can result in exceeding the maximum junction temperature, which could permanently damage the device. See the Thermal Information section of this document for more information about PowerPAD technology.

2.For operation above TA = 25°C, derate the THS7001 linearly to 2 W at the rate of 30.6 mW/°C and derate the THS7002 linearly to

2.33W at the rate of 35.9 mW/°C.
