Op-amps drive ADC for high-speed industrial solutions

03-11-2020 | Mouser Electronics | Power

Mouser now stocks Texas Instruments' TLV915x op-amps and ADS7128 12-bit ADC. Providing excellent precision and performance in small form factors, the op-amps and ADC work jointly to support a variety of industrial applications, comprising test and measurement equipment, factory automation, and data acquisition systems.

These low-offset voltage, low-noise op-amps, merge outstanding DC precision with robust AC performance. The 16V general-purpose devices offer rail-to-rail output, low offset, low offset drift, and 4.5 MHz bandwidth. The low-noise op-amps provide a wide differential input-voltage range, high output current of ±75mA, and high slew rate of 20V/µs, making them ideal for industrial use as well as for high-side and low-side current sensing.

The op-amps can drive the company's ADS7128 12-bit ADC, an eight-channel, multiplexed SAR-type device. The ADC's eight channels are able to be independently configured as digital inputs, digital outputs, or analog inputs. Working in either autonomous or single-shot conversion mode, the ADC communicates employing an I2C-compatible interface. The device is an integrated zero-crossing-detect module, allowing transient rejection and hysteresis near configurable threshold crossings. The ADC supports applications, comprising mobile robot CPU boards, digital multimeters, and rack servers.
